In fact, undocumented people pay into the system and never receive benefits. The Social Security Trustees build this into long term fiscal projections for the program because of how much this offsets long term debt in the program.

🗣️ Published today in @aeajournals.bsky.social. Ethan Lewis and I use a visa lottery, as a nationwide randomized experiment, to test the effects of foreign labor on US firms and workers. doi.org/10.1257/app.... A concise summary from @nber.org —> www.nber.org/digest/20221...

This is perhaps the most impressive #medical study I have seen in years: www.nature.com/articles/s41... It will save a lot of lives.

NEW: A spokesperson for U.S. Health and Human Services confirmed to Stateline on Friday that the agency is canceling 53 out of 67 grants, worth about $68 million, under the Teen Pregnancy Prevention Program, affecting grantees in more than two dozen states.

This study of four cohorts of French schoolchildren shows that the gender gap in math (girls falling behind) begins essentially immediately as soon as kids start school. They use the natural variation in kids' ages at school start to show that it's school entry, not age, that triggers the change.

Atheen nicely summarizes the paper. I will just add that the DCC issues we study are increasingly recognized in other contexts, e.g. discrimination www.annualreviews.org/content/jour... and demography onlinelibrary.wiley.com/doi/abs/10.1... where terminology like identity fluidity is often used.

After the Dobbs decision, patients experiencing miscarriages in states with abortion bans have fewer choices in the type of care they get, and they are receiving lower-quality care as well. My latest: www.theguardian.com/us-news/2026...

Mindel Sheps wrote many beautiful papers about the mathematics of demography. Her papers "On the person years concept in epidemiology and demography" in Millbank and "Shall we count the living or the dead?" in NEJM are my favorites. Also, she mentored Jane Menken!!!

A commentary I wrote on new research by Arun Hendi & Veronica Clevenstine showing that Black immigrant life expectancy in the US is extremely high -- high enough that increased immigration accounts for almost 15% of declining Black/White life exp gaps, 1994-2019 (pdf should be ungated at this link)

Finally, here's an absolute banger of an article, published just last month (Hoffman et al. 2026), showing how incredibly powerful the cohort patterning of influenza deaths is, in regular (not pandemic) years, corresponding to how circulating strains match up w what people were exposed to as kids

demoscapes.org is a visual atlas of demographic surfaces hosted at @mpidr.bsky.social. It is also my passion project growing out of my 2016 human mortality database explorer. Did you publish something containing Lexis surfaces? Consider reaching out and having your work featured on the site.

Every single one of the above choices tends to create a negative wage gap between H-1B workers and US workers. Not one of them is justifiable. There is a right way to do the analysis, so I did it right, in a new paper at @rfberlin.bsky.social —> www.rfberlin.com/network-pape...

Even if "singularities" could be ruled out it's way past time caring about GDP in the absence of indicators of what a specific growth path entails for human health and the natural environment.

The degree of randomness in individual survival is vastly underappreciated

Twin Cities' (Hennepin+Ramsey) counties filings for evictions up 40% in Jan 2026 over 2023-24 baseline @evictionlab.bsky.social. In raw counts, +9% to 1,330 in Jan 2026 from 1,220 in prior month. In baseline years (2023 & 2024), filings lower in Jans than Decs. evictionlab.org/eviction-tra...

Between 2013 and 2023, private equity ownership of US fertility clinics increased nearly tenfold, from 3.7% to over 32%, with affiliated sites responsible for the majority of #IVF cycles by 2023. ja.ma/49ubuWl

When relational, iterative engagement is key to building informal public health capacity both within government and among non-state actors, today’s policy’s payoff well into the future by building up these relationships. OTOH, this means today’s cuts will reverberate well into the future.

We are now accepting applications for our Annual Workshop on Formal Demography, taking place in-person at UC Berkeley on June 2-6, 2025. Deadline to apply is March 10. See more information on the workshop and how to apply here: populationsciences.berkeley.edu/wp-content/u... Please share widely!

Our two papers on abortion bans and fertility/infant mortality are now out. In 14 states w/ abortion bans, fertility increased 1.7% and infant mortality increased 6%. Key takeaway is that these impacts were disproportionately felt among those w/ greatest structural disadvantages. Links below.

A paper I've been working on for quite literally 10 years just came out It's a shitty time, for sure, but this paper is still cool and good, and I still want to you tell you all about it So gather 'round, folks, and hear the story of the 10 year paper! 1/n www.tandfonline.com/doi/full/10....

Elated to share that the dream team @stephcanizales.bsky.social, @drmirianma.bsky.social, Silvia Rodriguez Vega and I are getting ~$1.6 million from UCOP MRPI for our project Reimagining Refuge: California for Just Migrant Futures. Stay tuned for seed grants to CA scholars, artists, and activists!

This is an awesome team. Great opportunity for anyone finishing this AY working on repro health

As somebody who faced a frivolous SLAPP suit for standing up to flawed science (www.theguardian.com/science/2023...), I've been thinking a lot about this. I've been developing a table of resources along these lines. Suggestions on where/how best to share it are welcome.

I’ll say it again: the anti-HPV vaccines are a miracle 🌟 A beloved family friend is living with metastasized cervical cancer right now. Enough! This podcast ep with Kemi Doll is a great cervical cancer 101 podcasts.apple.com/us/podcast/1...
