"It would be straightforward to examine the geography of intermixing and to investigate results for cohabiting couples too."

In conjunction with what you have given us here, I think the cohabiting couples (and geography) would definitely be interesting. In addition, since the topic is, broadly, that of Americans mixing, are there any good ways to look at the parentage of children or what percentage of Americans have had a relationship outside of their race?

Thanks for all your work, it is always interesting and well presented, even if I have to smash my head on the desk to remember the stats and R programming I learned in the distant past.

Your percentage of women never-married by race differs sharply from that reported in these links by the Census. What do you think that is?

For example, the following chart shows that the percent of never-married women has increased from about 20% to 30% from 1970 to 2020: https://www.census.gov/content/dam/Census/library/visualizations/time-series/demo/families-and-households/ms-1b.pdf

You can see data by race based on Table MS-1 here: https://www.census.gov/data/tables/time-series/demo/families/marital.html.

For example, the spreadsheet shows that the never-married percentage among black women increased from 28% (2,248/8,108) in 1970 to 47% (8,709/18,339) in 2020, whereas your graph shows an increase from about 50% to 60% over the same time period.

One possibility is that your 2 "percentage of never-married" graphs contain people of all ages, including children, whereas the links I posted are limited to individuals aged 15 years or older (this would also explain why the never-married percentage decreased for some groups in your graphs whereas it increased for all groups in my links; over this time period, the adult-to-child ratio would have increased, which decreases the never-married percentage). You mention the results are "confounded by age", but it's not clear if that means it's unrepresentative or that it includes children. If the data includes children, I'm not sure how informative these 2 graphs are.
