I'm about 18 months and 20,000 words into the "pronatalism" tag on Family Inequality. Surely this means my book is almost done.

Long story short, revolution makes more sexy time. (Or, if you prefer, "coital frequency.") At least for Fins. Implications for pronatalism are clear.

Nice! The Rising, about a firefighter climbing to his death in a noble but ultimately futile effort to rescue innocent people from the fire. Little did he know.

Thanks to @cschmert.bsky.social, whose suggested explanation is closest to this illustration:

Suppose women have the same # of children as ever, but postpone to later ages. Then *right now* the population consists of younger women who are having few births *because they're waiting* and older women who are having few births *because they didn't*. The result is a low current fertility rate.

Why the total fertility rate falls for a while when women have children later, even though everyone ends up with the same number -- in one chart.

Stable younger motherhood

Alex Pretti was assaulted twice by federal agents while carrying his pistol and never drew it. Clearly that's not why he had it. I reckon it was to defend his people from some Kyle Rittenhouse type attacking the protestors. A heroic thought, IMO, and all the more tragic

Senate Democrats on Thursday blocked a spending package needed to keep the government open past a Friday midnight deadline, even as they continued negotiating with President Trump on a deal that could avert a shutdown and lead to new restrictions on his immigration crackdown.

Democrats Block Spending Package as D.H.S. Talks Continue

With about 36 hours to go before a shutdown deadline, the funding legislation stalled while Democrats sought a deal with President Trump to rein in his immigration crackdown.

I don't know this is a pretty modest swing given the scale of destruction he has wreaked.

Good people are trying to teach in the Florida state education system. Quitting might be good, but I don't blame people who stay. Those of us outside should condemn it and shun it as an institution while supporting individuals inside.

Florida launches statewide book burning, with Intro to Sociology textbook as kindling. Their state education system is a farce, a system for destroying knowledge and ideas in order to prevent critical thinking.

Florida Introduces “Sanitized” Sociology Textbook

The volume was created after a state review found that existing course materials violated a law prohibiting general education courses from teaching about systemic inequality. So far, at least two univ...

Two possible reasons: 1. they are not exactly the same people because they are separate sample surveys conducted every two years, 2: random sample variation because the samples are not that large. If it was a big difference I would be concerned.

141. For US women, the number of children born at all ages below 40 has fallen across cohorts born from the 1950s through the 1980s. But those born in the early 1980s (who just reached age 44) caught up, and their completed fertility was no lower than previous cohorts. Future TBD.

I have been grumbling about Census top-coding children ever born at 5 in CPS since 2018. But with rising nonresponse, which leads them to use other household info to impute, and it seems reasonable. Easy to end up imputing outliers www.census.gov/library/working-papers/2015/demo/SEHSD-WP2015-04.html
