Chasing Life podcast on making babies, or not

CNN’s Dr. Sanjay Gupta has a podcast called Chasing Life about coming out of the pandemic. Associate producer Grace Walker interviewed me for an episode titled, “Let’s Talk About Making Babies (Or Deciding Not To).” In it reporter Chloe Melas starts with the story of a Black couple (two women, one of them trans) seeking to have children. At about minute 21, she turns to the fertility decline in the US. The transcript of that part is below. This episode would be good for teaching.


Chloe Melas: But we can’t forget – not everyone wants to have children. And that’s OK. According to the CDC, the number of births in the United States fell by 4% last year – the largest annual decline since 1973. Given the global pandemic, for demographers like Philip Cohen of the University of Maryland, this isn’t too surprising.

Philip Cohen: What we’ve learned in the last century or so is that when there are crises birth rates go down. It’s partly deliberate, that is, people decide to hold off on having children, or decide against having children, because they’re unsure about the future, they’re unsure they’ll be able to care for them, they think they might lose their job, they think their mother might lose her job – all the things that go into the calculations of when and whether to have children.

CM: 2020 is not an outlier. Cohen says birthrates have been on a downward trend for quite a while.

PNC: We were sort of focusing on issues like work-family balance, childcare, healthcare, housing, the expenses of raising children, and the difficulty of raising children, which had been putting pressure on people to reduce their number of children. That’s the main reason. At the same time, when people have more opportunities to do other things in their lives, they’re also inclined to have fewer children, or delay having children. So especially for women, when opportunities improve, the number of children they have tends to go down, because on average they’re more likely to choose something else.

CM: Hispanic women in particular are seeing some of the largest declines. From 2007 to 2017 birth rates fell by 31%. Experts attribute this drop to more Hispanic women joining the workforce, and waiting longer to start families than previous generations. Overall, the data doesn’t lie. Fewer people are having kids. That could lead to smaller kindergarten classrooms, as well as larger demands on Social Security, given the aging population. But Cohen and others think there could be positives, too. For example, fewer people means less of an environmental impact on the planet. So it’s really a glass half empty, glass half full kind of situation. The point is, I think this pandemic has really made many of us reflect on what we want our future to look like, including our future families. Some have been inspired to freeze their eggs, some to seek out help for infertility, and some have decided against having kids while others have been inspired to do so.

Now in the Washington Post: The generation labels mean nothing. It’s time to retire them

Hard times and falling fertility in the United States

The text and figures of this short paper are below, and it’s also available as a PDF on SocArXiv, in more citable form. The Stata code and other materials are up as well, here. It’s pretty drafty — very happy to hear any feedback.

Preamble: When Sabrina Tavernise, Claire Cain Miller, Quoctrung Bui and Robert Gebeloff wrote their excellent New York Times piece, Why American Women Everywhere Are Delaying Motherhood, they elevated one important aspect of the wider conversation about falling fertility rates — the good news that women with improving economic opportunities often delay or forego having children because that’s what they’d rather do.

But it’s tricky to analyze this. Consider one woman they quote, who said, “I can’t get pregnant, I can’t get pregnant… I have to have a career and a job. If I don’t, it’s like everything my parents did goes in vain.” Or another, who is waiting to have children till she finishes a dental hygienist degree, who said, “I’m trying to go higher. I grew up around dysfunctional things. I feel like if I succeed, my children won’t have to.” If people can’t afford decent childcare (yet), or won’t have a job that pays enough to afford the parenting they want to provide until they finish a degree — so they delay parenthood while investing in their careers — are they not having a baby because there are promising opportunities, or because of economic insecurity? These are edge cases, I guess, but it seems like they extend to a lot of people right now. That’s what motivated me to do this analysis.


Hard times and falling fertility in the United States

by Philip N. Cohen

Abstract

Recent reports have suggested that falling fertility in the US since the 2008 recession is being driven by women with advantaged status in the labor market taking advantage of career opportunities. This paper takes issue with that conclusion. Although high incomes are associated with lower fertility in general, both in the cross section and over time (within and between countries), economic crises also lead to lower fertility. I offer a new descriptive analysis using data from the American Community Survey for 2000-2019. In the U.S. case, the fertility decline was widespread after the 2008 recession, but most concentrated among younger women. Although women with above average education have long had lower birth rates, the analysis shows that birth rates fell most for women in states with higher than average unemployment rates, especially among those with below average education. This is consistent with evidence that birth rates are falling, and births delayed, by economic insecurity and hardship.

Introduction

A New York Times article by Sabrina Tavernise et al. was titled, “Why American Women Everywhere Are Delaying Motherhood” (Tavernise et al. 2021). Although it did not provide a simple answer to the question, it did offer this: “As more women of all social classes have prioritized education and career, delaying childbearing has become a broad pattern among American women almost everywhere.” And it included a figure showing birth rates falling faster in counties with faster job growth. Reading that article, the writer Jill Filipovic concluded, “the women who are driving this downturn [in fertility] are those who have the most advantage and the greatest range of choices, and whose prospects look brightest” (Filipovic 2021). This paper takes issue with that conclusion.

Clearly, one driver of delayed childbearing is the desire to maximize career opportunities, but there is also the weight of uncertainty and insecurity, especially regarding the costs of parenting. Filipovic (2021) also wrote, “Children? In this economy?” These two tendencies appear to generate opposing economic effects: A strong economy gives mothers more rewarding opportunities that childrearing threatens (reducing fertility), while also providing greater economic security to make parenting more affordable and desirable (increasing fertility). These two pathways for economic influence on fertility trends are not easily separable in research – or necessarily exclusive in personal experience. In what follows I will briefly situate falling US fertility in the wider historical and global context, and then offer a descriptive analysis of the US trend in births from 2000 to 2019, focusing on relative education and state unemployment rates.

Review and context

Historically, economic growth and development have been key determinants of fertility decline (Herzer, Strulik, and Vollmer 2012; Myrskylä, Kohler, and Billari 2009), although by no means the only ones, and with coupling that is sometimes loose and variable (Bongaarts 2017). In the broadest terms, both historically and in the present, higher average incomes at the societal level are strongly associated with lower fertility rates; and this relationship recurs within the United States as well, as shown in the cross section in Figure 1.

Figure 1. Total fertility rate by GDP per capita: Countries and U.S. states, 2019. Note: Markers are scaled by population. US states linear fit weighted by population. Source: World Bank, US Census Bureau, National Center for Health Statistics, Bureau of Economic Analysis.

A lower standard of living is associated with higher birth rates. However, economic crises cause declines in fertility (Currie and Schwandt 2014), and this was especially true around the 2008 recession in the U.S. (Comolli 2017; Schneider 2015) and other high-income countries (Gaddy 2021). The crisis interrupted what had been a mild recovery from falling total fertility rates in high-income countries, leading to a decline from 1.74 in 2008 to 1.57 by 2019 (Figure 2).

Figure 2. Total fertility rate in the 10 largest high-income countries: 1990-2019. Note: Countries with at least $30,000 GDP per capita at PPP. Source: World Bank.

Figure 2 shows that the pattern of a peak around 2008 followed by a lasting decline is widespread (with the notable exceptions of Germany and Japan, whose TFRs were already very low), although the post-crisis decline was much steeper in the U.S. than in most other high income countries. Figure 3 puts the post-crisis TFR decline in global context, showing the change in TFR between the highest point in 2007-2009 and the lowest point in 2017-2019 for each country, by GDP per capita. (For example, the U.S. had a TFR peak of 2.12 in 2007, and its lowest point in 2017-2019 was 1.71 in 2019, so its score is -.41.) Fertility decline is positively associated with per capita income, as low-income countries continued the TFR declines they were experiencing before the crisis. However, among the high-income countries the relationship reversed (the inflection point in Panel A is $36,600, not shown). Thus, the sharp drop in fertility in the U.S. after the 2008 economic crisis is indicative of a larger pattern of post-crisis fertility trends. Globally, fertility is higher but falling in lower-income countries; fertility is lower in high-income counties, but fell further during the recent period of economic hardship or uncertainty. As a result of falling at both low and high ends of the economic scale, therefore, global TFR declined from 2.57 in 2007 to 2.40 in 2019 (by these World Bank data).

The mechanisms for these relationships – higher standard of living and rising unemployment both lead to lower fertility – defy simple characterization. The social scale (individual to global) may condition the relationship; there may be different effects of relative versus absolute economic wellbeing (long term and short term); development effects may be nonlinear (Myrskylä, Kohler, and Billari 2009); and the individual or cultural perception of these social facts is important as well (Brauner-Otto and Geist 2018). Note also that, as fertility rates fall with development, the question of having no children versus fewer has emerged as a more important distinction, which further complicates the interpretation of TFR trends (Hartnett and Gemmill 2020).

U.S. recessions

In the case of recent U.S. recessions, the negative impact on fertility was largest for young women. After the 2001 recession, birth rates only fell for women under age 25. In the wake of the more severe 2008 economic crisis, birth rates fell for all ages of women up to age 40 (above which rates continued to increase every year until 2020) although the drop was still steepest below age 25 (Cohen 2018). For the youngest women, births have continued to fall every year since, while those over age 35 saw some rebound from 2012 to 2019 (Figure 4). Clearly, during this period many women postponed births from their teens or twenties into their thirties and forties. The extent to which they will end up with lower fertility on a cohort basis depends on how late they continue (or begin) bearing children (Beaujouan 2020).

Figure 4. Annual change in U.S. births per 1,000 women, by age: 2001-2020. Source: National Center for Health Statistics.

Contrary to the suggestion that fertility decline is chiefly the result of improving opportunities for women, the pattern of delaying births is consistent with evidence that structural changes in the economy, the decline in goods-producing industries and the rise of less secure and predictable service industry jobs, are largely responsible for the lack of a fertility rebound after the 2008 recession, especially for Black and Hispanic women (Seltzer 2019). Lower education is also associated with greater uncertainty about having children among young people (Brauner-Otto and Geist 2018). For women in more precarious circumstances, especially those who are not married, these influences may be observed in the effect of unemployment rates on birth rates at the state level (Schneider and Hastings 2015). The available evidence supports the conclusion that the 2008 recession produced a large drop in fertility that did not recover before 2020 at least in part because the economic uncertainty it amplified has not receded – making it both a short-term and long-term event.

Birth rates recovered some for older women, however – over 30 or so – which is consistent with fertility delay. But this delay does not necessarily favor the opportunity cost versus economic constraint explanations. On one hand are people with higher levels of education (anticipated or realized) who plan to wait until their education is complete. On the other hand are those with less education who are most economically insecure, whose delays reflect navigating the challenges of relationship instability, housing, health care, childcare and other costs with lesser earning potential. This latter group may end up delaying either until they attain more security or until they face the prospect of running out of childbearing years. Both groups are deliberately delaying births partly for economic reasons, but the higher-education group is much more likely to have planned births while the latter have higher rates of unintended or mistimed births (Hayford and Guzzo 2016).

The opportunity cost of women’s childbearing, in classical models, is simply the earnings lost from time spent childrearing – the product of the hours of employment lost and the expected hourly wage (Cramer 1979). Although rising income potential for women has surely contributed to the long-run decline of fertility rates, in the U.S. that mechanism has not been determinative. Women experienced large increases in earnings for decades during which fertility rates did not fall. As the total fertility rate rose from its low point in 1976 (1.74) to the post-Baby Boom peak in 2007 (2.12) – defying the trend in many other high-income countries – the average weekly earnings of full-time working women ages 18-44 rose by 16% in constant dollars (Figure 5).

Figure 5. Median weekly earnings of full-time employed women ages 18-44, and total fertility rate. Source: Current Population Survey Annual Social and Economic Survey, and Human Fertility Database.

Clearly, other factors beyond lost earnings calculations are at work. However, there is no simple way to distinguish those who make direct cost comparisons, where investments in time and money take away from other needs and opportunities, from those who delay out of concern over future economic security, which weighs on people at all income levels and generates reluctance to make lifelong commitments (Pugh 2015). But the implications of these two effects are opposing. For people who don’t want to lose opportunities, a strong economy with abundant jobs implies lower fertility. For people who are afraid to commit to childrearing because of insecurity about their economic fortunes, a weak economy should decrease fertility. The experience of the post-2008 period provides strong evidence for the greater weight of the latter mechanism.

US births, 2000-2019

If opportunity costs were the primary consideration for women, one might expect an inverse relationship between job market growth and fertility rates: more jobs, fewer babies; fewer jobs, more babies. This is the pattern reported by Tavernise et al. (2021), who found that birthrates after the 2008 crisis fell more in counties with “growing labor markets” – which they attribute to the combination of improving opportunities for women and the high costs of childcare. However, their analysis did not attend to chronological ordering. They identified counties as having strong job growth if they were in the top quintile of counties for labor market percent change for the period 2007 to 2019, and compared them with counties in the bottom quintile of counties on the same measure with regard to birth rates (author correspondence). Thus, their analysis used a 2007-2019 summary measure to predict birth rates for each year from 1990 to 2019, making the results difficult to interpret.

In addition to using contemporaneous economic data, whereas Tavernise et al. (2021) used county-level birth rates, in this analysis I use individual characteristics and state-level data. I construct indicators of individual- and state-level relative advantage during the period before and after the 2008 economic crisis, from 2000 to 2019. Individual data are from the 2000-2019 American Community Survey (ACS) via IPUMS (Ruggles et al. 2021). I include in the analysis women ages 15-44, and use the fertility question, which asks whether they had a baby in the previous 12 months. I analyze this as a dichotomous dependent variable, using ordinary least squares regression. Results are graphed as marginal effects at the means, using Stata’s margins command. The sample size is 9,415,960 million women, 605,150 (6.4%) of whom had a baby in the previous year (multiple births are counted only once).

In models with controls, I control for age in five-year bins, race/ethnicity (White, Black, American Indian, Asian/Pacific Islander, Other/multiple-race, and Hispanic), citizenship (U.S.-born, born abroad to American parents, naturalized, and not a citizen), marital status (married, spouse absent, separated, divorced, widowed, and never married), education (less than high school, high school graduate, some college, and BA or higher degree), as well as (in some models) the state unemployment rate (lagged two years), and state fixed effects. State unemployment rates are from Local Area Unemployment Statistics (Bureau of Labor Statistics 2021). ACS person weights are used in all analyses.

For states, I use the unemployment rate in each state for each year, and divide the states at the median, so those with the median or higher unemployment for each year are coded as high unemployment states, and low unemployment otherwise (this variable is lagged two years, because the ACS asks whether each woman has had a birth in the previous 12 months, but does not specify the month of the birth, or the date of the interview). For individuals, the identification of economic advantage is difficult with the cross-sectional data I use here, because incomes are likely to fall in the year of a birth, and education may be determined endogenously with fertility as women age (Hartnett and Gemmill 2020), so income and education cannot simply be used to identify economic status. Instead, I identify women as low education if they have less than the median level of education for women of their age in their state for each year (using single years of age, and 26 categories of educational attainment), and high education otherwise. Thus, individual women in my sample are coded as in a high or low unemployment state relative to the rest of the country each year, and as having high or low education relative other women of their age and state and year. Using the ACS migration variable, I code women into the state they lived in the previous year, which is more likely to identify where they lived when they determined whether to have a baby (which also means I exclude women who were not living in the U.S. in the year before the survey).

Figure 6 shows the unadjusted probability of birth for women in high- and low-unemployment states for the period 2000-2019. This shows the drop in birth rates after 2008, which is steeper for women who live in high-unemployment states, especially before 2017. This is what we would expect from previous research on the 2008 financial crisis: a greater falloff in birth rates where the economy suffered more.

Figure 6. Probability of birth in the previous year: 2000-2019, by state unemployment relative to the national media (marginal effects at the means). Women ages 15-44. Based on state of residence in the previous year; unemployment lagged two years.

Next, I split the sample again by women’s own education relative to the median for those of the same age, year, and state. Those less than that median are coded as low education, those at or higher than the median are coded as high education. Figure 7 shows these results (again, unadjusted for control variables), showing that those with lower education (the top two lines) have higher birth rates throughout the period. After 2008, within both the high- and low-education groups, those in high-unemployment states had longer and steeper declines in birth rates (at least until 2019). The steepest decline is among low-education, high-unemployment women: those facing the greatest economic hardship at both the individual and state level. Finally, Figure 8 repeats the model shown in Figure 7, but with the control variables described above, and with state fixed effects. The pattern is very similar, but the differences associated with state unemployment are attenuated, especially for those with low education.

Figure 7. Probability of birth in the previous year: 2000-2019, by education relative to the age-state median, and state unemployment relative to the national media (marginal effects at the means). Women ages 15-44. Based on state of residence in the previous year; unemployment lagged two years.

Figure 8. Probability of birth in the previous year: 2000-2019, by education relative to the age-state median, and state unemployment relative to the national media, with controls for age, race/ethnicity, citizenship, marital status, and state fixed effects (marginal effects at the means). Women ages 15-44. Based on state of residence in the previous year; unemployment lagged two years.

Discussion

Although birth rates fell for all four groups of women in this analysis after the 2008 recession, these results reflect that paradoxical nature of economic trends and birth rates. Women with higher education (and greater potential earnings) have lower birthrates, consistent with the opportunity cost reasoning described in Tavernise et al. (2021) and elsewhere. However, women in states with higher unemployment rates – especially when they have high relative education – also have lower birthrates, and in these states saw greater declines after the 2008 crisis. This is consistent with the evidence of negative effects of economic uncertainty and stress. And it goes against the suggestion that stronger job markets drive down fertility rates for women with higher earning potential, at least in the post-2008 period. In the long run, perhaps, economic opportunities reduce childbearing by increasing job market opportunities for potential mothers, but in recent years this effect has been swamped by the downward pressure of economic troubles. US birth rates fell further in 2020, apparently driven down by the COVID-19 pandemic, which raised uncertainty – and fear for the future – to new heights (Cohen 2021; Sobotka et al. 2021). We don’t yet know the breakdown of the shifts in fertility for that year, but if the effects were similar to those of the 2008 economic crisis, we would expect to see greater declines among those who were most vulnerable.

Draft: Open letter to the Pew Research Center on generation labels

This post has been updated with the final signing statement and a link to the form. Thanks for sharing!

I have objected to the use of “generation” divisions and names for years (here’s the tag). Then, the other day, I saw this introduction to an episode of Meet the Press Reports, which epitomized a lot of the gibberishy nature of generationspeak (sorry about the quality).

OK, it’s ridiculous political punditry — “So as their trust in institutions wanes, will they eventually coalesce behind a single party, or will they be the ones to simply transform our political system forever?” — but it’s also generations gobbledygook. And part of what struck me was this: “millennials are now the largest generation, they have officially overtaken the Baby Boom.” Well-educated people think these things are real things, official things. We have to get off this train.

If you know the generations discourse, you know a lot of it emanates from the Pew Research Center. They do a lot of excellent research — and make a lot of that research substantially worse by cramming into the “generations” framework that they more than anyone else have popularized — have made “official.”

After seeing that clip, I put this on Twitter, and was delighted by the positive response:

So I wrote a draft of an open letter to Pew, incorporating some of the comments from Twitter. But then I decided the letter was too long. To be more effective maybe it should be more concise and less ranty. So here’s the long version, which has more background information and examples, followed by a signing version, with a link to the form to sign it. Please feel to sign if you are a demographer or other social scientist, and share the link to the form (or this post) in your networks.

Maybe if we got a lot of signatories to this, or something like it, they would take heed.


Preamble by me

Pew’s generation labels — which are widely adopted by many other individuals and institutions — encourage unhelpful social science communication, driving people toward broad generalizations, stereotyping, click bait, sweeping character judgment, and echo chamber thinking. When people assign names to generations, they encourage anointing them a character, and then imposing qualities onto whole populations without basis, or on the basis of crude stereotyping. This fuels a constant stream of myth-making and myth-busting, with circular debates about whether one generation or another fits better or worse with various of its associated stereotypes. In the absence of research about whether the generation labels are useful either scientifically or in communicating science, we are left with a lot of headlines drawing a lot of clicks, to the detriment of public understanding.

Cohort analysis and the life course perspective are important tools for studying and communicating social science. We should study the shadow, or reflection, of life events across people’s lives at a cultural level, not just an individual level. In fact, the Pew Research Center’s surveys and publications make great contributions to that end. But the vast majority of popular survey research and reporting in the “generations” vein uses data analyzed by age, cross-sectionally, with generational labels applied after the fact — it’s not cohort research at all. We shouldn’t discourage cohort and life course thinking, rather we should improve it.

Pew’s own research provides a clear basis for scrapping the “generations.” “Most Millennials Resist the ‘Millennial’ Label” was the title of a report Pew published in 2015. This is when they should have stopped — based on their own science — but instead they plowed ahead as if the “generations” were social facts that the public merely failed to understand.

This figure shows that the majority of Americans cannot correctly identify the generational label Pew has applied to them.

The concept of “generations” as applied by Pew (and many others) defies the basic reality of generations as they relate to reproductive life cycles. Pew’s “generations” are so short (now 16 years) that they bear no resemblance to reproductive generations. In 2019 the median age of a woman giving birth in the U.S. was 29. As a result, many multigenerational families include no members of some generations on Pew’s chart. For example, it asks siblings (like the tennis-champion Williams sisters, born one year apart) to identify as members of separate generations.

Perhaps due to their ubiquitous use, and Pew’s reputation as a trustworthy arbiter of social knowledge, many people think these “generations” are official facts. Chuck Todd reported on NBC News just this month, “Millennials are now the largest generation, they have officially overtaken the Baby Boom.” (NPR had already declared Millennials the largest generation seven years earlier, using a more expansive definition.) Pew has perhaps inadvertently encouraged these ill-informed perspectives, as when, for example, Richard Fry wrote for Pew, “Millennials have surpassed Baby Boomers as the nation’s largest living adult generation, according to population estimates from the U.S. Census Bureau” — despite the fact that the Census Bureau report referenced by the article made no mention of generations. Note that Chuck Todd’s meaningless graphic, which doesn’t even include ages, is also falsely attributed to the U.S. Census Bureau.

Generations are a beguiling and appealing vehicle for explaining social change, but one that is more often misleading than informative. The U.S. Army Research Institute commissioned a consensus study report from the National Academies, titled, Are Generational Categories Meaningful Distinctions for Workforce Management? The group of prominent social scientists concluded: “while dividing the workforce into generations may have appeal, doing so is not strongly supported by science and is not useful for workforce management. …many of the stereotypes about generations result from imprecise use of the terminology in the popular literature and recent research, and thus cannot adequately inform workforce management decisions.”

As one of many potential examples of such appealing, but ultimately misleading, uses of the “Millennial” generation label, consider a 2016 article by Paul Taylor, a former executive vice president of the Pew Research Center. He promised he would go beyond “clichés” to offer “observations” about Millennials — before describing them as “liberal lions…who might not roar,” “downwardly mobile,” “unlaunched,” “unmarried,” “gender role benders,” “upbeat,” “pre-Copernican,” and as an “unaffiliated, anti-hierarchical, distrustful” generation who nevertheless “get along well with their parents, respect their elders, and work well with colleagues” while being “open to different lifestyles, tolerant of different races, and first adopters of new technologies.” And their “idealism… may save the planet.”

In 2018 Pew announced that it would henceforth draw a line between “Millennials” and “Generation Z” at the year 1996. And yet they offered no substantive reason, just that “it became clear to us that it was time to determine a cutoff point between Millennials and the next generation [in] order to keep the Millennial generation analytically meaningful, and to begin looking at what might be unique about the next cohort.” In asserting that “their boundaries are not arbitrary,” the Pew announcement noted that they were assigning the same length to the Millennial Generation as they did to Generation X — both 16 years, a length that bears no relationship to reproductive generations, nor to the Baby Boom cohort, which is generally considered to be 19 years (1946-1964).

The essay that followed this announcement attempted to draw distinctions between Millennials and Generation Z, but it could not delineate a clear division, because none can be drawn. For example, it mentioned that “most Millennials came of age and entered the workforce facing the height of an economic recession,” but in 2009, the trough year for that recession, Millennials by Pew’s definition ranged from age 13 to 29. The other events mentioned — the 9/11 terrorist attacks, the election of Barack Obama, the launch of the iPhone, and the advent of social media — similarly find Millennials at a range of ages too wide to be automatically unifying in terms of experience. Why is being between 12 and 28 at the time of Obama’s election more meaningful a cohort experience than being, say, 18 to 34? No answer to this is provided, because Pew has determined the cohort categories before the logical scientific questions can be asked.

Consider a few other hypothetical examples. In the future, we might hypothesize that those who were in K-12 school during the pandemic-inflicted 2020-2021 academic year constitute a meaningful cohort. That 13-year cohort was born between 2003 and 2015, which does not correspond to one of Pew’s predetermined “generations.” For some purposes, an even narrower range might be more appropriate, such as those who graduated high school in 2020-2021 alone. Under the Pew generational regime, too many researchers, marketers, journalists, and members of the general public will look at major events like these through a pre-formed prism that distorts their ability to pursue or understand the way cohort life course experiences affect social experience.

Unlike the other “generations” in Pew’s map, the Baby Boom corresponds to a unique demographic event, painstakingly, empirically demonstrated to have begun in July 1946 and ended in mid-1964. And being part of that group has turned out to be a meaningful experience for many people — one that in fact helped give rise to the popular understanding of birth cohorts as a concept. But it does not follow that any arbitrarily grouped set of birth dates would produce a sense of identity, especially one that can be named and described on the basis of its birth years alone. It is an accident of history that the Baby Boom lasted 18 years — as far as we know having nothing to do with the length of a reproductive generation, but perhaps leading subsequent analysts to use the term “generation” to describe both Baby Boomers and subsequent cohorts.

The good researchers at Pew are in a tough spot (as are others who rely on their categories). The generations concept is tremendously appealing and hugely popular. But where does it end? Are we going to keep arbitrarily dividing the population into generations and giving them names — after “Z”? On what scientific basis would the practice continue? One might be tempted to address these problems by formalizing the process, with a conference and a dramatic launch, to make it even more “official.” But there is no scientific rationale for dividing the population arbitrarily into cohorts of any particular length for purposes of analyzing social trends, and to fix their membership a priori. Pew would do a lot more to enhance its reputation, and contribute to the public good, by publicly pulling the plug on this project.


Open letter to the Pew Research Center on generation labels

Sign the letter here.

We are demographers and other social scientists, writing to urge the Pew Research Center to stop using its generation labels (currently: Silent, Baby Boom, X, Millennial, Z). We appreciate Pew’s surveys and other research, and urge them to bring this work into better alignment with scientific principles of social research.

  1. Pew’s “generations” cause confusion.

The groups Pew calls Silent, Baby Boom, X, Millennial, and Z are birth cohorts determined by year of birth, which are not related to reproductive generations. There is further confusion because their arbitrary lengths (18, 19, 16, 16, and 16 years, respectively) have grown shorter as the age difference between parents and their children has lengthened.

  1. The division between “generations” is arbitrary and has no scientific basis.

With the exception of the Baby Boom, which was a discrete demographic event, the other “generations” have been declared and named on an ad hoc basis without empirical or theoretical justification. Pew’s own research conclusively shows that the majority of Americans cannot identify the “generations” to which Pew claims they belong. Cohorts should be delineated by “empty” periods (such as individual years, equal numbers of years, or decades) unless research on a particular topic suggests more meaningful breakdowns.

  1. Naming “generations” and fixing their birth dates promotes pseudoscience, undermines public understanding, and impedes social science research.

The “generation” names encourage assigning them a distinct character, and then imposing qualities on diverse populations without basis, resulting in the current widespread problem of crude stereotyping. This fuels a stream of circular debates about whether the various “generations” fit their associated stereotypes, which does not advance public understanding.

  1. The popular “generations” and their labels undermine important cohort and life course research

Cohort analysis and the life course perspective are important tools for studying and communicating social science. But the vast majority of popular survey research and reporting on the “generations” uses cross-sectional data, and is not cohort research at all. Predetermined cohort categories also impede scientific discovery by artificially imposing categories used in research rather than encouraging researchers to make well justified decisions for data analysis and description. We don’t want to discourage cohort and life course thinking, we want to improve it.

  1. The “generations” are widely misunderstood to be “official” categories and identities

Pew’s reputation as a trustworthy social research institution has helped fuel the false belief that the “generations” definitions and labels are social facts and official statistics. Many other individuals and organizations use Pew’s definitions in order to fit within the paradigm, compounding the problem and digging us deeper into this hole with each passing day.

  1. The “generations” scheme has become a parody and should end.

With the identification of “Generation Z,” Pew has apparently reached the end of the alphabet. Will this continue forever, with arbitrarily defined, stereotypically labeled, “generation” names sequentially added to the list? Demographic and social analysis is too important to be subjected to such a fate. No one likes to be wrong, and admitting it is difficult. We sympathize. But the sooner Pew stops digging this hole, the easier it will be to escape. A public course correction from Pew would send an important signal and help steer research and popular discourse around demographic and social issues toward greater understanding. It would also greatly enhance Pew’s reputation in the research community. We urge Pew to end this as gracefully as possible — now.

As consumers of Pew Research Center research, and experts who work in related fields ourselves, we urge the Pew Research Center to do the right thing and help put an end to the use of arbitrary and misleading “generation” labels and names.

Citizen Scholar: new book under contract

PN Cohen photo

My new book, Citizen Scholar, is under contract with Columbia University Press (thanks to the support of editor, and Editorial Director, Eric Schwartz).

Some of the writing I’ve been doing here is part of the book’s development, including the piece on “policy implications,” essays on transparency and accountability in research, as well as talks and materials about preprints, open science and the pandemic, politics and science, and others. It’s time for a book (and also more talks, if you’d like to invite me!). I will post essays and excerpts as I go, here, and I welcome your critiques, suggestions, and ideas. The first post describes my ambitions, and plan, for the book.

I love Family Inequality and everyone here but it seemed awkward to repeatedly post stuff for the new book under this heading. So I set up a blog style page, and I’ll post links here, too (and I’ll figure out you can subscribe, for those who want their blog posts via email).

Wish me luck!

The American Sociological Association is collapsing and its organization is a perpetual stagnation machine

I am at the end of a three-year term as an elected member of the American Sociological Association (ASA) Committee on Publications, during which time, despite some efforts, I achieved none of the goals in my platform. I would like to say I learned a lot or whatever, but I didn’t. I enjoyed the time spent with colleagues at the meetings (and we did some rubber stamping and selecting editors, which someone had to do), but beyond that it was a waste of time. Here are some reflections.

First, some observations about sociology as a discipline, then about the ASA generally, and then about the situation with the Committee on Publications.

Sociology

Sociology has occupied a rapidly declining presence in US higher education for two decades. The percentage of bachelor’s, masters, and PhD degrees that were awarded in sociology peaked at the end of the last century:

soc degree share

Looking just at the number of PhDs awarded, you can see that among the social sciences, since the 2009 recession (scaled to 0 on this figure), sociology is one of the social sciences disciplines that has slipped, while psychology, economics, business, and political science have grown (along with STEM disciplines).

phds relative to 2009

The American Sociological Association

So, sociology as an academic discipline is in decline. But how is ASA doing — is it fair for me to say “collapsing” in the title of this post? The shrinking of the discipline puts a structural squeeze on the association. In order to maintain its organizational dimensions it would need a growing share of the sociology milieu. The prospects for that seem dim.

On the plus side, the association publishes several prominent journals, which were the ostensible subject of our work on the publications committee. Metrics differ, but two ASA journals are in the top ten sociology journals by five-year citation impact factor in Web of Science (American Sociological Review and Sociology of Education [the list is here]). In the Google Scholar ranking of journals by h5-index, which uses different subject criteria, only one (ASR) is in the top 20 of sociology journals, ranking 20th out of the combined top 100 from economics, social science general, sociology, anthropology, and political science  (the list is here). In terms of high-impact research, among the top 100 most cited Web of Science sociology papers published in 2017 (an arbitrarily chosen recent year), seven were published in ASA journals (five in American Sociological Review [the list is here]). The 2020 Almetric Top 100 papers, those gaining the most attention in the year (from sources including news media and social media), includes 35 from humanities and social sciences, none of which were published by ASA (although several are by sociologists). So ASA is prominent but not close to dominant within sociology, which is similarly situated within the social sciences. In terms of publications, you can’t say ASA is “collapsing.” (Plus, in 2019 ASA reported $3 million in revenue from publications, 43 percent of its total non-investment income.)

But in terms of membership, the association is leading the way in the discipline’s decline. The number of members in the association fell 24 percent from 2007 to 2019, before nosediving a further 16 percent last year. Relative to the number of PhDs completing their degrees, as one scale indicator, membership has fallen 42 percent since 2007 — from 26 paying members per PhD awarded to 15. Here are the trends:

asa membership

Clearly, the organization is in a serious long-term decline with regard to membership. How will an organization of sociologists, including organizational sociologists, react to such an organizational problem? Task force! A task force on membership was indeed seated in 2017, and two years later issued their report and recommendations. To begin with, the task force reported that ASA’s membership decline is steeper than that seen by 11 other unnamed disciplinary societies:

discsocmem

They further reported that only 36 percent of members surveyed consider the value of belonging to ASA equal to or greater than the cost, while 48 percent said it was overpriced. Further, 69 percent of members who didn’t renew listed cost of membership as an important reason, by far — very far — the most important factor, according to their analysis. Remarkably, given this finding, the report literally doesn’t say what the member dues or meeting registration fees are. Annual dues, incidentally, increased dramatically in 2013, and now range from $51 for unemployed members to $368 for those with incomes over $150,000 per year, apparently averaging $176 per member (based on the number of members and membership revenue declared in the audit reports).

Not surprisingly, then, although they did recommend “a comprehensive review of our membership dues and meeting registration fee structures,” they had no specific recommendations about member costs. Instead they recommended: Create new ways for sociologists to create subgroups within the association, “rethink the Annual Meeting and develop a variety of initiatives, both large and small,” remove institutional affiliations from name badges and make the first names bigger, give a free section membership to new members (~$10 value), anniversary- instead of calendar-based annual pricing, hold the meeting in a wider “variety of cities,” more professional development (mechanism unspecified), more public engagement, change the paper deadline a couple of weeks and consider other changes to paper submission, and provide more opportunities for member feedback. Every recommendation was unanimously approved by the association’s elected council. The following year membership fell another 16 percent, with some unknown portion of the drop attributable to the pandemic and the canceled annual meeting.

With regard to the membership crisis, my assessment is that ASA is a model of organizational stagnation and failure to respond in a manner adequate to the situation. The sociologist members, through their elected council, seem to have no substantial response, which will leave it to the professional staff to implement emergency measures as revenue drops in the coming years. One virtually inevitable outcome is the association further committing to its reliance on paywalled journal publishing and the profit-maximizing contract with Sage, and opposing efforts to open access to research for the public.

Committee on Publications

But it is on the publications committee, and its interactions with the ASA Council, that I have gotten the best view of the association as a perpetual stagnation machine.

I can’t say that the things I tried to do on the publications committee would have had a positive effect on ASA membership, journal rankings, majors, or any other metric of impact for the association. However, I do believe what I proposed would have helped the association take a few small steps in the direction of keeping up with the social science community on issues of research transparency and openness. In November I reported how, more than two years ago now, I proposed that the association adopt the Transparency and Openness Promotion Guidelines from the Center for Open Science, and to start using their Open Science Badges, which recognize authors who provide open data, open materials, or use preregistration for their studies. (In the November post I discussed the challenge of cultural and institutional change on this issue, and why it’s important, so I won’t repeat that here.)

The majority of the committee was not impressed at the beginning. At the January 2019 meeting the committee decided that an “ad hoc committee could be established to evaluate the broader issues related to open data for ASA journals.” Eight months later, after an ad hoc committee report, the publications committee voted to “form an ad hoc committee [a different one this time] to create a statement regarding conditions for sharing data and research materials in a context of ethical and inclusive production of knowledge,” and to, “review the question about sharing data currently asked of all authors submitting manuscripts to incorporate some of the key points of the Committee on Publications discussion.” The following January (2020), the main committee was informed that the ad hoc committee had been formed, but hadn’t had time to do its work. Eight months later, the new ad hoc committee proposed a policy: ask authors who publish in ASA journals to declare whether their data and research materials are publicly available, and if not why not, with the answers to be appended in a footnote to each article. And then the committee approved the proposal.

Foolishly, last fall I wrote, “So, after two years, all articles are going to report whether or not materials are available. Someday. Not bad, for ASA!” Yesterday the committee was notified by ASA staff that, “Council is pleased that Publications Committee has started this important discussion and has asked that the conversation be continued in light of feedback from the Council conversation.” In other words, they rejected the proposal and they’ll tell us why in another four months. There is no way the proposal can take effect for at least another year — or about four years after the less watered-down version was initially proposed, and after my term ends. It’s a perpetual stagnation machine.

Meanwhile, I reviewed 24 consecutive papers in ASR, and found that only four provided access to the code used and at least instructions on how to find the data. Many sociologists think this is normal, but in the world of academic social science, this is not normal, it’s far behind normal.

I don’t know if the Council is paying attention to the Task Force on Membership, but if they were it might have occurred to them that recruiting people to run for office, having the members elect them based on a platform and some expertise, having them spend years on extremely modest, imminently sensible proposals, and then shooting those down with a dismissive “pleased [you have] started this important discussion” — is not how you improve morale among the membership.

Remember that petition?

While I’m at it, I should update you on the petition many of you signed in December 2019, in opposition to the ASA leadership sending a letter to President Trump against a potential federal policy that would make the results of taxpayer-funded research immediately available to the public for free — presumably at some cost to ASA’s paywall revenues. At the January 2020 meeting the publications committee passed two motions:

  1. For the Committee on Publications to express opposition to the decision by the ASA to sign the December 18, 2019 letter.
  2. To encourage Council to discuss implications of the existing embargo and possible changes to the policy and to urge decisionmakers to consult with the scientific community before making executive orders.

We never heard back from the ASA Council, and the staff who opposed the petition were obviously in no rush to follow up on our entreaty to them, so it disappeared. But I just went back to March 2020 Council minutes, and found this profoundly uninformative tidbit:

Council discussed a recent decision of ASA’s authorized leadership to sign a letter expressing concern about an executive order related to scientific publishing rumored to be coming out with almost no notice or consultation with the scientific community. A motion was made by Kelly to affirm ASA’s policy for making time sensitive decisions about public statements and to confirm that the process was properly followed in this instance. Seconded by Misra. Motion carried with 16 for and 2 abstentions.

This doesn’t mention that the substance of the dispute, that the publications committee objected to the leadership’s statement, or the fact that more than 200 people signed a letter that read, in part: “We oppose the decision by ASA to sign this letter, which goes against our values as members of the research community, and urge the association to rescind its endorsement, to join the growing consensus in favor of open access to scholarship, including our own.” To my knowledge no member of the ASA leadership, whether elected sociologists or administrative staff, has responded publicly to this letter. Presumably, the terrible statement sent by the ASA leadership still represents the position of the association — the association that speaks for a rapidly dwindling number of us.

Side note: An amazing and revealing thing happened in the publications committee meeting where we discussed this statement in January 2020. The chair of the committee read a prepared statement, presumably written by the ASA staff, to introduce the voting on my proposal:

The committee has a precedent that many of you are already aware of, of asking people to leave for votes on the proposals they submitted…. This practice is designed to ensure that the committee members can have a full and open discussion. So, Philip, I’d like to ask you to recuse yourself now for the final two items, which you can simply do by hanging up the phone…

Needless to say, I refused to leave the meeting for the discussion on my proposal, as there is no such policy for the committee. (If you know of committee meetings where the person making a proposal — an elected representative — has to leave for the discussion and vote, please let me know.) It was just an attempt to railroad the decision, and other members stepped in to object, so they dropped it. The motion passed, and council ignored it, so seriously who cares, but still. (The minutes for this meeting don’t reflect this whole incident, but I have verbatim notes.) 

You will forgive me if, after this multi-year exercise in futility, I am not inclined to be optimistic regarding the Taskforce on Membership’s Recommendation #10: “Enhance and increase communications from ASA to members and provide opportunities for ASA members to provide ongoing feedback to ASA.” I have one more meeting in my term on the publications committee, but it doesn’t seem likely I’ll be there.

What is life expectancy? (video)

My YouTube career may have peaked in 2015, with the now-classic video, Total Fertility Rate, which has been viewed almost 30,000 times (124 likes!). Since then the technical quality has improved, but not the viewership.

Recently I heard someone say (sorry, I can’t remember who) that they were looking for a short video explaining what life expectancy is. This was after the CDC reported that US life expectancy in the first half of 2020 decreased by 1 year, which generated some confusion. Outside of secondary effects, the pandemic did reduce life “expectancy” for people it didn’t kill, and here we are (still alive, so far) reading about it, so how could our life expectancy have been affected? did last year’s deaths mean people would live less long in the future? I said somewhere on twitter than “life expectancy” is a bad name for this common statistic, and I think it is. I don’t have a better name for it, though, and it’s probably to late to change anyway.

So, to help meet the current need, and to try to reach my past video glory, yesterday I produced, “What is life expectancy?“, a 6-minute explainer, using 3 graphs, to help people understand. I didn’t discuss the recent COVID results so as not to date the video, and I hope it will be useful in the future (that it has a long life expectancy).

Here it is:

Basic self-promotion

Five years ago today I wrote a post called “Basic self promotion” on here. There has been a lot of work and advice on this subject in the intervening years (including books, some of which I reviewed here). So this is not as necessary as it was then. But it holds up pretty well, with some refreshing. So here is a lightly revised version. As always, happy to have your feedback and suggestions in the comments — including other things to read.

Present yourself. PN Cohen photo: https://flic.kr/p/2hyYzqs.

If you won’t make the effort to promote your research, how can you expect others to?

These are some basic thoughts for academics promoting their research. You don’t have to be a full-time self-promoter to improve your reach and impact, but the options are daunting and I often hear people say they don’t have time to do things like run a Twitter account or write for blogs and other publications. Even a relatively small effort, if well directed, can help a lot. Don’t let the perfect be the enemy of the good. It’s fine to do some things pretty well even if you can’t do everything to your ideal standard.

It’s all about making your research better — better quality, better impact. You want more people to read and appreciate your work, not just because you want fame and fortune, but because that’s what the work is for. I welcome your comments and suggestions below.

Present yourself

Make a decent personal website and keep it up to date with information about your research, including links to freely available copies of your publications (see below). It doesn’t have to be fancy. I’m often surprised at how many people are sitting behind years-old websites. (I recently engaged Brigid Barrett, who specializes in academics’ websites, to redesign mine.)

Very often people who come across your research somewhere else will want to know more about you before they share, report on, or even cite it. Your website gives your work more credibility. Has this person published other work in this area? Taught related courses? Gotten grants? These are things people look for. It’s not vain or obnoxious to present this information, it’s your job. I recommend a good quality photo, updated at least every five years.

Make your work available

Let people read the actual research. For work not yet “published” in journals, post drafts when they are ready for readers (a good time is when you are ready to send it to a conference or journal – or earlier if you are comfortable with sharing it). This helps you establish precedence (planting your flag), and allows it to generate feedback and attract readers. It’s best to use a disciplinary archive such as SocArXiv (which, as the director, I highly recommend) or your university repository, or both. This will improve how they show up in web searches (including Google Scholar) indexed for things like citation or grant analysis, and archived. You can also get a digital object identifier (DOI), which allows them to enter the great stream of research metadata. (See the SocArXiv FAQ for more answers.)

When you do publish in journals, prefer open-access journals because it’s the right thing to do and more people can read your work there. If a paper is paywalled, share a preprint or postprint version. On your website or social media feeds, please don’t just link to the pay-walled versions of your papers, that’s the click of death for someone just browsing around, plus it’s elitist and antisocial. You can almost always put up a preprint without violating your agreements (ideally you wouldn’t publish anywhere that won’t let you do this). To see the policies of different journals regarding self-archiving, check out the simple database at SHERPA/RoMEO, or, of course, the agreement you signed with the journal.

I oppose private sites like Academia.edu, ResearchGate, or SSRN. These are just private companies making a profit from doing what your university and its library, and nonprofits like SocArXiv are already doing for the public good. Your paper will not be discovered more if it is on one of these sites.

I’m not an open access purist, believe it or not. (If you got public money to develop a cure for cancer, that’s different, then I am a purist.) Not everything we write has to be open access (books, for example), but the more it is the better, especially original research. This is partly an equity issue for readers, and partly to establish trust and accountability in all of our work. Readers should be able to see our work product – our instruments, our code, our data – to evaluate its veracity (and to benefit their own work). And for the vast majority of readers who don’t want to get into those materials, the fact they are there increases our collective accountability and trustworthiness. I recommend using the Open Science Framework, a free, nonprofit platform for research sharing and collaboration.

Actively share your work

In the old days we used to order paper reprints of papers we published and literally mail them to the famous and important people we hoped would read and cite them. Nowadays you can email them a PDF. Sending a short note that says, “I thought you might be interested in this paper I wrote” is normal, reasonable, and may be considered flattering. (As long as you don’t follow up with repeated emails asking if they’ve read it yet.)

Social media

If you’re reading this, you probably use at least basic social media. If not, I recommend it. This does not require a massive time commitment and doesn’t mean you have to spend all day doomscrolling — you can always ignore them. Setting up a public profile on Twitter or a page on Facebook gives people who do use them all the time a way to link to you and share your profile. If someone wants to show their friends one of my papers on Twitter, this doesn’t require any effort on my part. They tweet, “Look at this awesome new paper @familyunequal wrote!” (I have some vague memory of this happening with my papers.) When people click on the link they go to my profile, which tells them who I am and links to my website.

Of course, a more active social media presence does help draw people into your work, which leads to exchanging information and perspectives, getting and giving feedback, supporting and learning from others, and so on. Ideally. But even low-level attention will help: posting or tweeting links to new papers, conference presentations, other writing, etc. No need to get into snarky chitchat and following hundreds of people if you don’t want to. To see how sociologists are using Twitter, you can visit the list I maintain, which has more than 1600 sociologists. This is useful for comparing profile and feed styles.

Other writing

People who write popular books go on book tours to promote them. People who write minor articles in sociology journals might send out some tweets, or share them with their friends on Facebook. In between are lots of other places you can write something to help people find and learn about your work. I still recommend a blog format, easily associated with your website, but this can be done different ways. As with publications themselves, there are public and private options, open and paywalled. Open is better, but some opportunities are too good to pass up – and it’s OK to support publications that charge subscription or access fees, if they deserve it.

There are also good organizations now that help people get their work out. In my area, for example, the Council on Contemporary Families is great (I’m a former board member), producing research briefs related to new publications, and helping to bring them to the attention of journalists and editors. Others work with the Scholars Strategy Network, which helps people place Op-Eds, or the university-affiliated site The Society Pages, or others. In addition, there are blogs run by sections of the academic associations, and various group blogs. And there is Contexts (which I used to co-edit), the general interest magazine of ASA, where they would love to hear proposals for how you can bring your research out into the open (for the magazine or their blog).


For more on the system we use to get our work evaluated, published, transmitted, and archived, I’ve written this report: Scholarly Communication in Sociology: An introduction to scholarly communication for sociology, intended to help sociologists in their careers, while advancing an inclusive, open, equitable, and sustainable scholarly knowledge ecosystem.

A few months ago I did some reading about viruses and other parasites, inspired by the obvious, but also those ants that get commandeered by cordyceps fungi, as seen in this awesome Richard Attenborough video:

Besides the incredible feat of programming ants to disseminate fungus spores, the video reveals two other astounding facts about this system. First, worker ants from afflicted colonies selflessly identify and remove infected ants and dump their bodies far away, reflecting intergenerational genetic training as well as the ability to gather and process the information necessary to make the diagnosis and act on it. And second, there are many, many cordyceps species, each evolved to prey upon only one species, reflecting a pattern of co-evolution between host and parasite.

This led me to reading about colony defenses in general, including not just ants but things like wasps and termites that leave chemical protection for future generations, and bees getting together to make hive fevers to ward off parasitic infections. I don’t find a video of exactly a hive fever, but this one is similar: It’s bees using their collective body temperature to cook a predatory hornet to death:

Incredible. That got me thinking about how information management and dissemination is vital to colony-level defenses against parasites. They need to process and transmit information to work together in the arms race against parasites (especially viruses) that usually evolve much more rapidly than they do.

And you may know where this is going: How the US failed against SARS-CoV-2. In an information arms-race, life and death struggle against a parasitic virus that mutates exponentially faster than we can react — who knows how many experimental trials it took to design SARS-CoV-2? — this kind of efficient information system is what we need. And it worked in some ways, as humanity identified the virus and shared the data and code necessary to take action against it. But clearly we failed in other ways — communicating with our fellow citizens, dislodging the disinformation and misinformation that clouded their understanding and led so many to sacrifice themselves at the behest of a corrupt political organization and its demented leader.

Is this social evolution, I asked (despairingly), in which the Chinese system of government proves its superiority for survival at the colony level, while the US democratic system chokes on its own infected lungs. Worse, is the virus programming us to exacerbate our own weaknesses — yanking our social media chains and our slavery-era political institutions, like the rabies virus, which infects the brain and then explodes out through the salivary glands of a zombified attack animal. Colonies of ants rise or fall based on how they respond to parasites, which themselves are evolving to control ant behavior, as they evolve together. How exceptional are humans? Maybe we just do it faster, in social evolutionary time, rather than across many generations of breeding. Fascinating, but kind of dark. lol.

Anyway, naturally my concern is with information systems and scholarly communication. How human success against the virus has come from the rapid generation and dissemination of science and public health information (including preprints and data sharing). And failure came from disinformation and information corruption. Dr. Birx in the role the rabid raccoon, watching herself lose her grip on scientific reality as the authoritarian leader douses the public health information system with bleach and sets it on fire with an ultraviolet ray gun “inside the body.”

So I wrote a short paper titled, “Host, parasite, and failure at the colony level: COVID-19 and the US information ecosystem,” and posted it on SocArXiv: socarxiv.org/4hgam.* It includes this table:

Family Demography Seminar syllabus, 2021 edition

PN Cohen photo: https://flic.kr/p/2jw1ZhA.

This week it’s back to teaching Family Demography, a graduate seminar in the sociology department. This year a majority of the students are from other departments around campus, and of course the whole thing will be online. So we’ll see! I added a few weeks of pandemic related readings. And some things I never read before. Feel free to follow along. Feedback welcome.

This is the schedule, with readings. A lot of them are paywalled, I’m sorry to say, but you might have access to them. (You can always try sci-hub, which has stolen most academic articles for you, so you don’t have to steal them yourself.)
