JFC. This introduction by Hanna Rosin is completely wrong. Dean Spears absolutely wants to alarm you. And those are not "cold, hard numbers." In 60 years we may start a trajectory which could - *over centuries* - reduce population to a size we saw a century ago. www.theatlantic.com/politics/arc...

“Historically, no one lived past age 35”

"I’ve heard *so* many versions of this claim, including recently from a menopause doctor (implying menopause is not “natural” because noone lived long enough to go through it). Every time someone states this “fact,” a demographer loses a piece of their soul"
There Were Still Old People When Life Expectancy Was 35.
A demography myth that won't die

A *null* result I'm very proud of!

Led by Rustam Romaniuc, 35 coauthors from all over France tested nudge interventions to boost voter turnout.

None worked, and we are possibly not surprised -- but a well-powered null result *is* a result!

CIC/SDC Webinar – Overview of IPUMS and Linking Historical Data
The State Data Center and Census Information Center networks co-hosted this webinar on Wednesday, April 23, 2025 to give an overview of the data available on IPUMS and give some examples of how members of our networks are using it. A recording of the webinar can be found below or at this YouTube link on the Texas Demographic Center’s page. 2025 Webinar Slides_IPUMS and Linking Historical DataDownload Speakers: David Van Riper, Director of Spatial Analysis at the Minnesota Population Center, presented first with an overview of the the types of data available on IPUMS, with specific details about the time series and crosswalks of Census data that are available as part of IPUMS NHGIS. Matthew Ruther, Director of the Urban Studies Institute at the University of Louisville and Lead of the Kentucky State Data Center, gave a presentation about using full-count Census data and IPUMS’s Multigenerational Longitudinal Panel (MLP) to study urban change. Jeff Howison, Senior Research Analyst in the Minnesota State Demographic Center and Lead of the Minnesota State Data Center, used IPUMS data to study demographic trends in Minnesota homeownership. We were unable to feature his work in this webinar due to time constraints, but we will highlight his work in a future webinar. If you have a topic that you’d like to share or see covered in one of these webinars, reach out to Monica Cruz (monica.cruz@utsa.edu) or Doug White (douglas.white@lsus.edu). We’d love to hear from you!

Switzerland relies heavily on direct-democratic institutions to decide on a wide range of political issues. Since 1848, more than 600 direct-democratic votes have taken place at the national level. H...

This article is really good. Among everything coming out around LMs in sociology, this is top of the list for me. They frame text classification at a Natural Language Inference problem, and use BERT(MNLI) to produce an "entailment" score for document-claim pairs. Reproducible, careful, usable work.
