I am actively searching for a remote internship or graduate fellowship (in 2026) in social, demographic, health, or social policy research. I would appreciate any ideas, suggestions, recommendations, or leads. Thank you!🙏🏾

"We are entering a post-transition world in which the tools and theories that served demography so well are under strain—especially when it comes to anticipating future fertility," writes Anne Goujon in a new #ScienceExpertVoices article. scim.ag/44uUwnT
The demographic future that we do not know about
The demographic future of the planet has rarely been as questioned as it is today. For much of the 20th century, the demographic transition theory provided a clear narrative: With modernization and de...

[Due to huge interests in this, I post it here as well] I came across this interesting demography problem on X. It looks obvious until you actually think about it. And if you ask GPT, it will not give you the correct answer!

Births fluctuate, but over five decades fertility in the EU27 was remarkably similar: almost all countries had a total fertility rate between 1.5 and 1.9. Ireland was the exception, at 2.4.

🚨 The Economist has been telling you for years that polygamy causes civil war by locking men out of marriage. A new article with @rebeccasear.bsky.social and @anthrolog.bsky.social explains that the demography of marriage markets doesn't actually work that way. 🧵

When asked if Jesus “will return to Earth someday,” more than half of all U.S. adults (55%), including three-quarters of Christians, said this will happen.
www.pewresearch.org/short-reads/...
When asked if Jesus “will return to Earth someday,” more than half of all U.S. adults (55%), including three-quarters of Christians, say this will happen. Protestants in the evangelical (92%) and historically Black (86%) traditions are more likely than other Christians to say there will eventually be a second coming of Jesus. Roughly four-in-ten Americans either do not believe Jesus will return to Earth (25%) or say they do not believe in Jesus (16%). Respondents who said they believe Jesus will return to Earth were also asked how certain they are that this will happen during their lifetime. One-in-ten Americans say they believe the second coming of Jesus will definitely or probably occur during their lifetime, 27% are not sure if Jesus will return in their lifetime, and 19% say the return of Jesus will definitely or probably not occur during their lifetime. The proportion of Americans who say they believe Jesus will definitely or probably return during their lifetime is higher among Protestants in the historically Black tradition (22%) and evangelical Protestants (21%), and lower among Catholics (7%) and mainline Protestants (6%). And the share of Black (19%) and Hispanic (14%) Americans who believe that the second coming of Jesus will likely occur during their lifetime is greater than the corresponding share of White, non-Hispanic Americans (8%).

Does anyone want to be formal demography reading buddies? I have a bunch of areas I’m trying to read up on and I feel like I’d get it faster if I had someone to explain results to and ask questions of.

Thanks to @gabriconti.bsky.social & colleagues for this excellent paper bringing attention to the economic impacts of menopause.

Hopefully the big Oprah menopause TV special last night provides some new RDD opportunities! #econsky #demography #menopause

Men suffer significantly more loneliness, and almost no one is referring merely to gfs when they talk about it. There are many who do not have friends, aren't close to their family, and don't even make small talk. The demography of this means it's facile to frame it as individual failing.

1/ If it feels like a tsunami of bad news right now, I’m here to cheer you up with one trend that is moving in a positive direction:

➡️ Age-specific rates of #dementia have decreased substantially since 1984.

2/ It’s true that an aging population will bring higher *numbers* of dementia cases. One study estimated the number of US adults living with dementia will rise from 5 million in 2019 to 10 million in 2050.

Meanwhile, a graduate student has been waiting more than 9 months for a first round review at a major journal.

Because nothing says "we support our junior scholars" more than knee-capping their publication chances in advance of what is shaping up to be one of worst US job markets in recent memory.

These correlations between state death rates and percent Evangelical show an unsteady increase. It is not due to increase in the Evan population, it is very steady in all the states. I think it is the Evans relying on religion. Note the Evan effect when vaccinations became available.🧪 💡 #sociology
