New COVID-19 and Health Disparities lecture

I recorded a new version of the lecture I created last spring: COVID-19 and Health Disparities. It defines health disparities, introduces the theory of fundamental causes, and then describes COVID-19 disparities by race/ethnicity and age with reference to education and occupational inequality. For intro sociology students.

Using data from Bureau of Labor Statistics (inspired by this piece from Justin Fox), I showed the percentage of workers working at home according to the median wage in their occupations, illustrating how people in lower-paid occupations aren’t working at home, while professionals and managers are:

And, using age- and race/ethnic-specific mortality rates from CDC, with population denominators from the 2018 ACS (I don’t know why I can’t find the denominators CDC uses), I made this:

The greatest race/ethnic disparities are in the working ages, which suggests they are driven at least partly by occupational inequality.

The lecture 23 minutes, slides with references and links are here.

Race and racism in America (video)

In my Social Problems class we’re spending the next few weeks on race, racial inequality, and racial politics. Step one is this lecture on race and racism.

After a tangent on racial identity, idealism and its enemies, I address biology and race, describing the classic racist racial categories in relation to vast human diversity in Africa and the world overall, with discussion of biological evolution and the sources of human variation. Then I turn to the US and discuss social definition and self-definition, race versus ethnicity, definitions of racism and discrimination, and how the Census Bureau measures US race and ethnicity, before summarizing current and projected race/ethnic composition. And I used the new Zoom feature where your PowerPoint slides are the virtual background (which is harder than it looks because your image isn’t mirrored while you speak!).

It’s 35 minutes. The slides are here, CC-BY: To see all my videos, visit my YouTube channel.

Measuring inequality, and what the Gini index does (video)

I produced a short video on measuring inequality, focusing on the construction of the Gini index, the trend in US family inequality, and an example of using it to measure world inequality. It’s 15 minutes, intended for intro-level sociology students.

I like teaching this not because so many of my students end up calculating and analyzing Gini indexes, but because it’s a readily interpretable example of the value of condensing a lot of numbers down to one useful one — which opens up the possibility of the kind of analysis we want to do (Going up? Going down? What about France? etc.). It also helps introduce the idea that social students of inequality are systematic and scientific, and fun for people who like math, too.

The video is below, or you can watch it (along with my other videos) on YouTube. The slides are available here, including one I left out of the video, briefly discussing Corrado Gini and his bad (fascist, eugenicist) politics. Comments welcome.

Pandemic Social Problems, with video and partial reading list

With a lecture and reading list, almost ready to start class.

Almost 6 months ago, on March 2, I had an informal COVID-19 debriefing with 50 students in my Social Problems class. Some of what I said came true, and I’m glad (sort of?) none of it was completely wrong (though we didn’t actually hit 100 million worldwide confirmed cases in May). For a reality check I go back to this Twitter thread, where I jotted down what I told them:

Now, as I prepare to teach the course online next week, I have updated my overview lecture, which has grown to 40 minutes.

Beyond some fundamentals, I’m tossing out the traditional Social Problems course outline and just doing the pandemic and related issues this semester, so this is the introductory lecture. I expect to record some more lectures. If I decide they’re not too embarrassing to share I’ll put them on my YouTube channel (which you can apparently subscribe to if you want to be notified of the videos). Feel free to use them for whatever you like, and pass along your feedback.

The course doesn’t start till next week, so I don’t have everything together yet, but I have a lot of readings, some for me and some for the students, which I’m sharing below.

Happy to have more suggestions, too.

Family violence and abuse lecture, with COVID pandemic discussion

I recorded a video lecture on the subject of family violence and abuse, including intimate partner violence, rape, and sexual abuse, with some discussion of the COVID pandemic implications.

The 24-minute video is on YouTube here:

COVID lecture for Social Problems class

On March 2, I opened up my Social Problems class to questions on the emerging coronavirus epidemic. One of the things I did was show them a graph of worldwide cases on a log scale, and told them that it implied the world would have a million cases a month later. We hit that number to the day two days ago. Here are my notes from that day:

A month later, with school indeed canceled (which I had given only a 10-20% on March 2, I recorded this 28-minute lecture for them as an update. Feel free to use any part of it any way you like*:

* Two notes, having watched it over myself and gotten some feedback:

  1. At 4:40 I said of the graph shown: “The number of new cases confirmed by testing, every day, in the country, since February.” I should have said, “in the world” (as the figure is labeled).
  2. It’s been pointed out that social distancing and other responses to the outbreak are not the only thing that differentiate trajectories of the different outbreaks around the country. Also relevant is the demography of the area, including age, as well as health status and healthcare infrastructure. Those factors will emerge as the pandemic matures.
