New paper on how to calculate a multistate death distribution! What's that, you ask? Usually, we plot a death distribution by age at death. But age at death is the sum of our time spent in different states. If we split time between being healthy or not, then the distribution is multistate (1/3)
a multistate death distribution. This plot has healthy years in x, unhealthy years in y, and x+y (descending diagonals) is age at death. We display the death distribution as filled contours. The health measure in question is ADLs, which has a high mortality penalty, so the distribution mostly hugs the lower axis. state expectancies and total life expectancy converge on a point. SHARE data, females, ADL, 2015-17.

HMDHFDplus updated to account for minor web design update of @hmdatabase.bsky.social . If you started experiencing funny behavior when using the package to read HMD data from the web, just reinstall; it's already on CRAN. #rstats #demography #mortality

Let's be clear: no one should be taking medical advice from the man who told Americans to inject bleach.

To moms worried about the Tylenol they took while pregnant: you deserve better than being RFK Jr's scapegoat.

And to the autism community: you are loved exactly as you are.

So, a university president fired a professor because they taught a course that discussed there being more than two genders, and now the university president is being fired for not having fired the professor quickly enough, is where we're at. www.nytimes.com/2025/09/18/u...

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.

A blog from me on why social science infrastructures matter. I talk about the value of social science data collections & data services (especially @ukdsimpact.bsky.social), current opportunities and challenges (including AI, the growth of TREs & training), & what we're doing about them at ESRC.

Recalling that COVID still ranks in the top 10 causes of death in the US since 2023, while it ranked third in 2021-2022! So it had not only an important impact during the height of the pandemic, but it also remained a leading cause of death overall thereafter.

Persistent minimizing of the COVID death toll hits me especially hard in the #demography feels. To be clear:

➡️ Over one million Americans died of COVID-19.

➡️ Official COVID deaths were likely undercounted, not overcounted.

Here's a short happy-go-lucky 🎶 parody about the way that
Robert F. Kennedy Jr. is now collapsing American healthcare - based off #PaulSimon's toe-tapping "Me and Julio Down by the Schoolyard".

It's called: "Measles and Polio Down in the Schoolyard."

I don't have any official news to break yet, but it is no secret that we have been exploring an organizational footprint outside of the US for a couple of years. I expect we will have updates w/in several weeks. Just one of several potential proactive steps related to this issue.
