Father care: The more things don’t change, the more they stay the same

The U.S. Census Bureau has released its new report on childcare. This provides a good followup treatment for the hyperventilation induced by fear of fathers taking over (or being relegated to) childcare.*

First, the trend that fits my story of stalled gender progress. Among married fathers with employed wives, how many are providing the “primary care” for their children? That is, among the various childcare arrangements the children are in while their mother is at work, how many are in their fathers’ care more than in any other arrangement? Answer: 10%, which is virtually unchanged from a quarter-century ago:

Source:  U.S. Census Bureau, Who’s Minding the Kids? Child Care Arrangements: Spring 2011. (There was a methodology change in 1997, before which Census asked parents to name their primary arrangement, which they now calculate from the hours in each arrangement.)

Not a lot of change for a quarter century in which we’re told everything has changed.

However, in fairness to the change-is-happening community, here is the trend for the percentage of fathers who say they are providing ANY care to their children while their mothers were at work.

Source: As above.

I don’t give this much weight since it might reflect greater sensitivity to the importance of saying fathers provide care, but there you have it: it’s higher, and it shows some increases up until the early 1990s, which is when gender equality in general stalled on many indicators. Since the mid-1990s: Nothing.

Please note these figures don’t show the total contribution of fathers, but only reflects those married with children, whose wives are employed.

One interesting source of father care is mothers’ shiftwork. As Harriet Presser reported two decades ago, the 24/7 economy stimulates some task sharing among couples. In the current report, the Laughlin writes:

Preschoolers whose mothers worked nights or evenings were more likely to have their father as a child care provider than those with mothers who worked a day shift (42 percent and 23 percent, respectively)

* The report was written by Lynda Laughlin — have you credited a government bureaucrat by name for something valuable they did today?

Gender and family time: change and stall visualized

The Pew Research Center put out a report this month titled, “Modern Parenthood: Roles of Moms and Dads Converge as They Balance Work and Family.” It analyzes trends in time use among men and women in families, showing the big changes since the 1960s, and adds Pew’s own survey data on attitudes and perceptions. Lots of interesting information.

But what jumped out at me was that the stall in progress did not feature much in Pew’s narrative, written by Kim Parker and Wendy Wang. I really noticed that when the Joy Cardin show featured the report on Wisconsin Public Radio, and Cardin’s intro was this:

Family gender roles are converging, according to a new survey from the Pew Research Center. Father’s have more than doubled the time they spend on housework. More moms are paid to work outside the home. (The audio is here.)

Those facts are true, but old news – older than the new news, which is that nothing much has happened since the early 1990s. Here are the trends, in Pew’s nice graphics. See if you can find the stall point in each figure.

The last one, parents’ child care time, is the only one that shows continued real progress, albeit slower, in the last decade.

I favor three explanations for this gender stall:

• Work-family policy, as described by Stephanie Coontz here.
• Cultural trends toward “egalitarian essentialism,” which “blends aspects of feminist equality and traditional motherhood roles” (e.g., intensive parenting mania), as described by David Cotter, Joan Hermsen and Reeve Vanneman here.
• Weaker government enforcement of anti-discrimination law, as described in the new book Documenting Desegregation, by Don Tomaskovic-Devey and Kevin Stainback.

These explanations do not exclude others.

Data visualizations: Is U.S. society becoming more diverse?

Trying to summarize a few historical trends for the last half century (because what else is there to do?), I thought of framing them in terms of diversity.

Diversity is often an unsatisfying concept, used to describe hierarchical inequality as mere difference. But inequality is a form of diversity — a kind of difference. And further, not all social diversity is inequality. When people belong to categories and the categories are not ranked hierarchically (or you’re not interested in the ranking for whatever reason), the concept of diversity is useful.

There are various ways of constructing a diversity index, but I use the one sometimes called the Blau index, which is easy to calculate and has a nice interpretation: the probability that two randomly selected individuals are from different groups.

Example: Religion

Take religion. According to the 2001 census of India, this was the religious breakdown of the population:

RELIGION	Number	Proportion
Hindus	827,578,868	.805
Muslims	138,188,240	.134
Christians	24,080,016	.023
Sikhs	19,215,730	.019
Buddhists	7,955,207	.008
Jains	4,225,053	.004
Others	6,639,626	.006
Religion not stated	727,588	.001
Sum of squared proportions		.667
Diversity		.333

Diversity is calculated by summing the squares of the proportions in each category, and subtracting the sum from 1. So in India in 2001, if you picked two people at random, you had a 1/3 chance of getting people with different religions (as measured by the census).

Is .33 a lot of religious diversity? Not really, it turns out. I was surprised to read on the cover of this book by a Harvard professor that the United States is “the world’s most religiously diverse nation.” When I flipped through the book, though, I was disappointed to see it doesn’t actually talk much about other countries, and does not seem to offer the systematic comparison necessary to make such a claim.

With our diversity index, it’s not hard to compare religious diversity across 52 countries using data from World Values Survey, with this result:

The U.S. is quite diverse — .66 — but a number of countries rank higher.

Of course, the categories are important in this endeavor. For example, Turkey and Morocco are both 99% “Muslim.” So is Iraq, but in Iraq that population is divided between people who identify as Muslim, Shia and Sunni, so Iraq is much more diverse. You get the same effect by dividing up the Christians in the U.S., for example.

Increasing U.S. diversity

Anyway, back to describing the last half century in the U.S. On four important measures I’ve got easy-to-identify increasing diversity. What do you think of these (with apologies for the default Microsoft color schemes):

The last one is a little tricky. It’s common to report that the median age at marriage has increased since the 1950s (having fallen before the 1950s). But I realized it’s not just the average increasing, but the dispersion: More people marrying at different ages. So the experience of marriage is not just shifting rightward on the age distribution, but spreading out. Here’s another view of the same data:

These are corrected (5/11/2013) from the first version of this post. I have now calculated these using the this report from the National Center for Health Statistics for 1960, and comparing it with the 2011 American Community Survey for those married in the previous year.

I have complained before that using the 1950s or thereabouts as a benchmark is misleading because it was an unusual period, marked by high conformity, especially with regard to family matters. But it is still the case that since then diversity on a number of important measures has increased. Over the period of several generations, in important ways the people we randomly encounter are more likely to be different from ourselves (and each other).

All hands dimorphic: Gnomeo and Juliet edition

I previously complained about Tangled‘s 75%-male cast and extreme sex dimorphism in the romantic leads, as seen in this hand shot:

Keeping to my policy of two-year delays in movie reviews, let me add the same complaint about Gnomeo and Juliet, the charming adaptation from Disney’s Touchstone imprint. Here, a writing team of 8 men and 2 women (including Shakespeare) gives us a named cast of 14 men and 7 women, in a love story featuring these two adorable garden gnomes:

He’s only a little taller, and (judging by the gray beard) a little older. And in the movie she demonstrates bravery and feats of strength, as is now the norm. But look at those hands! Take a closer look:

What is it about hands that makes it so essential for men and women to have such differences? In the “man hands” episode of Seinfeld we learned how distressing it can be for a man to find out the woman to whom he was attracted has large hands.

That scene required a hand double. In real life, men’s and women’s hands differ on average but with a lot of overlap in the distributions — lots of men have hands smaller than lots of women. But in animation the gloves are off — and Disney is free to pair up couples who are many standard deviations apart in hand size. If real people commonly had this range of hand sizes, would such an extreme difference be considered desirable?

When regular old mothers aren’t old-enough looking

As I wrote about the older-birth-mothers issue recently (first, and then), I didn’t comment on the photo illustrations people are using with the stories. But when an alert reader sent this one to me, from Katie Roiphe’s post in Slate, I couldn’t help it:

Something about that picture and “women in their late 30s or 40s” rubbed my correspondent the wrong way, or rather, led her to write, “Late 30s or early 40s?!?”

Since this was from a legit website that credits its stock agency, I was able to visit Thinkstock and search for the photo. Sure enough:

Of course, it’s not news, so the title “Middle-aged woman holding her newborn grandson” doesn’t make it a less true illustration of the older-mother phenomenon than one captioned “Desperate aging woman clings to feminist myth that it’s OK to delay childbearing.” But it gives you an idea of what the Slate editor was looking for in the stock photo.

I looked around a little, and found one other funny one. Another Slate essay, this one by Allison Benedikt, was reprinted in Canada’s National Post, and they laid it out like this:

When I visited the Getty Images site, I discovered this picture was taken in China. Here’s how it’s presented:

This one, which is a picture of real people, looks like it could be a grandmother, or maybe more likely a caretaker. Regardless, it’s sold as an illustration of a story about China’s elderly having too few grandchildren to take care of them, which is vaguely related to the content of the story, but that’s not what the Post’s caption points to:

It’s true that older parents are more established and experienced but many of those experiences are, from a genetic point of view, negative, says Allison Benedikt.

Anyway, there were others where the women looked pretty old for the story, but I couldn’t find them in the catalogs, so I stopped.

This is all relevant to one of my critiques of these stories, which is that they make it seem like having children at older ages has become more common than it was in the past. That’s true compared with 1980, but not 1960. The difference is it’s more likely to be their first child nowadays. So Benedikt is way off when she writes,

Remember how there was that one kid in your high school class whose parents weresooooo old that it was weird and creepy? That’s all of us now. Oops.

As I showed, 40-year-old women are less likely to have children now than they were when she was a kid. And when Roiphe writes of the “50-year-old mother in the kindergarten class [who] attracts a certain amount of catty interest and disapproval,” she should be aware that the disapproval – which I don’t doubt exists – is not about the increased frequency of older mothers, but about how people think about them.

I guess any of these stories could also have been illustrated with my own photo, from Taiwan, which I used to illustrate a post about low fertility rates — implying this presumed grandmother was happy because she at least has a grandchild. (You’re welcome to use the picture for that purpose, free clip-art searchers of the future, but please don’t describe it was a birth mother and her child.)

Poverty Poses a Bigger Risk to Pregnancy Than Age

Originally published in TheAtlantic.com.

The problem of income inequality often gets forgotten in conversations about biological clocks.

The dilemma that couples face as they consider having children at older ages is worth dwelling on, and I wouldn’t take that away from Judith Shulevitz’s essay in the New Republic, “How Older Parenthood Will Upend American Society,” which has sparked commentary from Katie Roiphe,Hanna Rosin, Ross Douthat, and Parade, among many others.
The story is an old one—about the health risks of older parenting and the implications of falling fertility rates for an aging population—even though some of the facts are new. But two points need more attention. First, the overall consequences of the trend toward older parenting are on balance positive, both for women’s equality and for children’s health. And second, social-class inequality is a pressing—and growing—problem in children’s health, and one that is too easily lost in the biological-clock debate.

Older mothers

First, we need to distinguish between the average age of birth parents on the one hand versus the number born at advanced parental ages on the other. As Shulevitz notes, the average age of a first-time mother in the U.S. is now 25. Health-wise, assuming she births the rest of her (small) brood before about age 35, that’s perfect.

Consider two measures of child well-being according to their mothers’ age at birth. First, infant mortality:

Source: Centers for Disease Control.

Health prospects for children improve as women (and their partners) increase their education and incomes, and improve their health behaviors, into their 30s. Beyond that, the health risks start accumulating, weighing against the socioeconomic factors, and the danger increases.

Second, here is the rate of cognitive disability among children according to the age of their mothers at birth, showing a very similar pattern:

Source: Calculations made for my working paper, available here. To match up children with their birth parents in the Census, I had to limit the sample to children living with two married parents, where both are in their first marriage, so it’s a pretty select group.

Again, the lowest risks are to those born when their parents are in their early 30s, a pattern that holds when I control for education, income, race/ethnicity, gender, and child’s age.

When mothers older than age 40 give birth, which accounted for 3 percent of births in 2011, the risks clearly are increased, and Shulevitz’s story is highly relevant. But, at least in terms of mortality and cognitive disability, an average parental age in the late 20s and early 30s is not only not a problem, it’s ideal.

Unequal health

But the second figure above hints at another problem—inequality in the health of parents and children. On that purple chart, a college graduate in her early 40s has the same risk as a non-graduate in her late 20s. And the social-class gap increases with age. Why is the rate of cognitive disabilities so much higher for the children of older mothers who did not finish college? It’s not because of their biological clocks or genetic mutations, but because of the health of the women giving birth.

For healthy, wealthy older women, the issue of aging eggs and genetic mutations from fathers’ run-down sperm factories is more pressing than it is for the majority of parents, who have not graduated college.

If you look at the distribution of women having babies by age and education, it’s clear that the older-parent phenomenon is disproportionately about more-educated women. (I calculated these from the American Community Survey, because age-by-education is not available in the CDC numbers, so they are a little different.)

Most of the less-educated mothers are giving birth in their 20s, and a bigger share of the high-age births are to women who’ve graduated college—most of them married and financially better off. But women without college degrees still make up more than half of those having babies after age 35, and the risks their children face have more to do with high blood pressure, obesity, diabetes, and other health conditions than with genetic or epigenetic mutations. Preterm births, low birth-weight and birth complications are major causes of developmental disabilities, and they occur most often among mothers with their own health problems.

Most distressing, the effects of educational (and income) inequality on children’s health have been increasing. Here are the relative odds of infant mortality by maternal education, from 1986 to 2001, from a study in Pediatrics. (This compares the odds to college graduates within each year, so anything over 1.0 means the group has a higher risk than college graduates.)

This inequality is absent from Shulevitz’s essay and most of the commentary about it. She writes, of the social pressure mothers like her feel as they age, “Once again, technology has given us the chance to lead our lives in the proper sequence: education, then work, then financial stability, then children”—with no consideration of the 66 percent of people who have reached their early 30s with less than a four-year college degree. For the vast majority of that group, the sequence Shulevitz describes is not relevant.

In fact, if Shulevitz had considered economic inequality, she might not have been quite as worried about advancing parental age. When she worries that a 35-year-old mother has a life expectancy of just 46 more years—years to be a mother to her child—the table she consulted applies to the whole population. She should breathe a little bit easier: Among 40-year-old white college graduateswomen are expected to live an average extra five years compared with those who have a high school education only.

When it comes to parents’ age versus social class, the challenges are not either/or. We should be concerned about both. But addressing the health problems of parents—especially mothers—with less than a college degree and below-average incomes is the more pressing issue—both for potential lives saved or improved and for social equality.

Have Obama haters lost traction?

Maybe it’s because Donald Trump isn’t really a true hero to anti-socialist, anti-Muslim, racist Americans.

For whatever reason, there has been a real slump in the number of people typing “obama gun” (will he take our guns away?), “obama muslim” (the idea used to run at about 20%), “obama socialist” (the republic “hangs in the balance“), and “obama citizen” (thank you, Snopes) into the Google search box since the 2008 election.

Here’s the Google trend (and the search link):

We don’t know how much these fears, versus other concerns, will affect votes against him this year, although there have been some good efforts to track the effects of anti-Black racism on his vote tally.

Naturally, not everyone who Googles these things believes the underlying stories or myths. But it seems likely they either believe them, are considering them, heard someone repeat them, or are arguing with someone who believes them, etc. So I’m guessing – just guessing – that these trends track those beliefs.

But maybe four years of Obama as an actual president has softened up the hard-line hatred in some quarters. What do you think?

Yo, how big is that yogurt bucket?

People don’t know how much they’re eating.

A recent experiment found that people eat more when the container is larger, even when the portion size is not. They gave Belgian college students a container of M&Ms and parked them in front of a TV, with some cover story. The students were randomly assigned to three groups, medium-portion/small-container, medium-portion/large-container, and large-portion/large-container. These were the results: The ones who got the large container ate more, whether it was full or not (the difference between the two wasn’t significant). These kinds of experiments continuously suggest that distractions, distortions and other apparently irrelevant information and events routinely have large effects on people’s eating practices (here’s an extensive review). One infamous study showed that even people served 14-day-stale popcorn at the movies ate 34% more when it was served in a large container. In an earlier popcorn study, researchers found that people given large containers not only ate more, but were less able to report how much they ate. They concluded:

When a food is eaten from a large container, it appears easy to lose track of how much one eats. Even if the food were to taste relatively unfavorable, eating it from a large container may cause one to overeat because they lose track of how much they have consumed.

About that yogurt tub All this occurred to me when I visited one of our many local Frozenyo franchise outlets. It’s a self-serve frozen yogurt place where you pay one price by weight no matter what you put in your bucket. The trick that impressed me is the bucket — there is only one size, and it’s very large. But you can’t judge how big it is because there’s nothing to compare it with — no sizes or prices on the wall, no mini cup for kids — just one stack of identical buckets. So the person who posted this picture on Yelp probably thought she had a reasonable size serving, since the thing is barely half full:

There are three possible ways to judge your self-served serving size. You can go by the tub (“I filled it half way”), you can go by the person next to you (“sheesh!”), or you can look at the cartoon penguins on the wall:

How much is the penguin eating? I took home one of the buckets, and measured the volume of water it holds: 18 ounces. In comparison, a standard kid-sized serving bowl, the kind some people use to give their kids ice cream at home, holds 12 ounces:

An innocent child used to half a bowl of ice cream — in the bowl on the left — might be pretty steamed if you served her this:

According to the serving size information on the back wall of Frozenyo, I think that’s about 1.5 servings, or 150 calories of the nonfat variety, before toppings. The penguin’s overflowing bowl is 5.0 servings. With no toppings that’s 500 calories. If you pile it with M&Ms, sprinkles, hot fudge, Captain Crunch, coconut topping and fresh kiwis, who knows. It’s not really that many calories to consume — the same number as a single slice of banana bread at Starbucks.

But the point is you don’t know how much you’re eating. One Yelp reviewer cautioned that you can get a stomach ache after eating at Frozenyo, because “your eyes are bigger than your stomach.” I think it’s because the dump-truck sized delivery vehicle you eat it out of is bigger than your stomach.

But most reviewers love it for the individual control over serving size and toppings, and the reasonable price ($.39 per ounce by weight, or $5-$6 for a typical load).* I think it’s a winning business model, with low labor costs, because all you need is one person to pour the mix into the machines and another to weigh the tubs and swipe credit cards. According to the company’s ambitious map, there are still 46 states with “territory available.”

If I were them, I would increase the bucket size by 5% per year. I doubt anyone would notice.

Debunking Hanna Rosin, stop The End of Rape story edition

You can’t get 18 pages into Hanna Rosin’s blockbuster myth-making machine The End of Men, before you get to this (on page 19):

One of the great crime stories of the last twenty years is the dramatic decline of sexual assault. Rates are so low in parts of the country — for white women especially — that criminologists can’t plot the numbers on a chart. “Women in much of America might as well be living in Sweden,* they’re so safe,” says criminologist Mike Males.

That’s ridiculous, as I’ll show. Rape is difficult to measure, partly because of limiting state definitions, but the numbers are consistent enough from different sources to support the conclusion that reported rape in the United States has become less common in the last several decades — along with violent crime in general. This is good news. Here is the rate of reported “forcible rape” (of women) as defined by the FBI’s crime reporting system, the Uniform Crime Reports.** See the big drop — and also that the rate of decline slowed in the 2000s compared with the 1990s: Source: Uniform Crime Reports, 2010. The claim in Rosin’s book — which, like much of the book, is not sourced in the footnotes — is almost too vague to fact-check. What is “much of the country,” and what is a number “so low” that a criminologist “can’t plot” it on a chart? (I’m no criminologist, but I have even plotted negative numbers on a chart.) But even though she makes things up and her publisher apparently doesn’t care, we must resist the urge to just ignore it. The book is getting a lot of attention, and it’s climbing bestseller lists. Just staying with the FBI database of reported rates, they do report them by state, so we can look for that “much of the country” she’s talking about. I made a map using this handy free tool. Source: FBI Uniform Crime Reports, 2010, Table 47.

The lowest state rate is 11.2 per 100,000 (New Jersey), the highest is 75 (Alaska).

You can also get the numbers for 360 metropolitan areas. For these, the average rate of forcible rape reported was 31.5 per 100,000 population. One place, Carson City, Nevada, had a very low rate (just one reported in 2010), but no place else had a rate lower than 5.1. (You can see the full list here.)

I have no trouble plotting numbers that low. I could even plot numbers as low as those reported by police in Europe, where, according to the European Sourcebook of Crime and Criminal Justice Statistics, for 32 countries in 2007, the median rate was just 5 per 100,000 — which is lower than every U.S. metropolitan area for 2010 (except Carson City, Nevada).

These police reports are under-counts compared with population surveys that ask people whether they have been the victim of a crime, regardless of whether it was reported to police. According to the government’s Crime Victimization Survey (CVS), 65% of rape/sexual assault is not reported. The CVS rate of rape and sexual assault (combined) was 70 per 100,000 in 2010. That does reflect a substantial drop since 2001 (although there was also a significant increase from 2009 to 2010).

And what about the “for white women especially” part of Rosin’s claim? According to the Crime Victimization Survey (table 9), the white victimization rate is the same as the national average: 70 per 100,000.

I hope it’s true, as Rosin says, that “what makes [this era] stand out is the new power women have to ward off men if they want to.” But it’s hard to see how that cause is served by inventing an end of rape.

*That is an ironic reference, because Sweden actually has very high (for Europe) rate reported rape, which has been attributed to its broad definition and aggressive attempts at prosecution and data collection.

** Believe it or not, this was their definition: “the carnal knowledge of a female forcibly and against her will. Attempts or assaults to commit rape by force or threat of force are also included; however, statutory rape (without force) and other sex offenses are excluded.” That is being changed to include oral and anal penetration, as well as male victims, but data based on those changes aren’t reported yet.

End-of-Men-Richer-Sex reality check, 40 years of pants edition

In 2010, 28% of wives were earning more than their husbands. And wives were 8-times as likely as their husbands to have no earnings.

I still don’t have my copies of The End of Men, by Hanna Rosin, or The Richer Sex, by Liza Mundy. But I’ve read enough of their excerpts to plan out some quick data checks.

Both Rosin and Mundy say women are rapidly becoming primary earners, breadwinners, pants-wearers, etc., in their families. It is absolutely true that the trend is in that direction. Similarly, the Earth is heading toward being devoured by the Sun, but the details are still to be worked out. As Rosin wrote in her Atlantic article:

In feminist circles, these social, political, and economic changes are always cast as a slow, arduous form of catch-up in a continuing struggle for female equality.

Which is right. So, where are we now, really, and what is the pace of change?

For the question of relative income within married-couple families, which is only one part of this picture – and an increasingly selective one – I got some Census data for 1970 to 2010 from IPUMS.

I selected married couples (heterogamous, throughout this post) in which the wife was in the age range 25-54, with couple income greater than $0. I added husbands’ and wives’ incomes, and calculated the percentage of the total coming from the wife. The results show and increase from 7% to 28% of couples in which the wife earns more than the husband:

(Thanks to the NYTimes Magazine for the triumphant wife image).

Please note this is not the percentage of working wives who earn more. That would be higher — Mundy calls it 38% in 2009 — but it wouldn’t describe the state of all women, which is what you need for a global gender trend claim. This is the percentage of all wives who earn more, which is what you need to describe the state of married couples.

But this 51% cutoff is frustratingly arbitrary. No serious study of power and inequality would rest everything on one such point. Earning 51% of the couple’s earnings doesn’t make one “the breadwinner,” and doesn’t determine who “wears the pants.”

Looking at the whole distribution gives much more information. Here it is, at 10-year intervals:

These are the points that jump out at me from this graph:

• Couples in which the wife earns 0% of the income have fallen from 46% to 19%, but they are still 8-times as common as the reverse — couples where the wife earns 100%.
• There have been very big proportionate increases in the frequency of wives earning more — such as a tripling among those who earn 50-59% of the total, and a quadrupling among those in which the wife earns it all.
• But the most common wife-earning-more scenario is the one in which she earns just over half the total. Looking more closely (details in a later post) shows that these are mostly in the middle-income ranges. The poorest and the richest families are most often the ones in which the wife earns 0%.

Maybe it’s just the feminist in me that brings out the stickler in these posts, but I don’t think this shows us to be very far along on the road to female-dominance.
