French, Polish, and Turkish prisons have super low escape rates. In Macedonia staying in prison almost looks optional. The difference between Germany and Austria is also stunning.

Are you working with Belgian register data in a cross-national/comparative project (population, health, inequality, life course, etc.)?
I’m preparing a symposium proposal for SLLS 2026 in Brussels (1–3 July) and I’m looking for short talks.
Please DM or comment if interested!

"Does this handle survival plots too?" asked @load-dependent.bsky.social
Yes it does! See below for RECOVERY.
Only catch is it doesn't like the dotted lines that appear in some survival plots (because the PDF geometry treats this as lots of little separate lines rather than one single entry).

Ukip have submitted a new logo and slogan to the Electoral Commission, swapping the £ pound sterling symbol for a cross, that looks very much like it is modelled on the Iron Cross used by Prussia & Germany 1871-1918 and Hitler's Nazi regime from 1933-45

MUST READ: great work, pedagogical, astounding US-OECD differences.
If there's one empirical insight I'd want everyone to understand about American politics, it's this:
America's problems are solved problems. Just not here.
What would change if the US simply matched the average of 31 peer democracies? Not Denmark or Norway. Just the middle of the pack. 🧵

Grand plaisir de partager ce texte que je mijote depuis un moment à propos du retour des discours natalistes que l’on croyait définitivement enterrés. Mais dans cette période de backlash généralisé, on pouvait s’attendre à ce que les vieilles lunes sur la démographie tentent de se remettre en selle.

“Reclaiming academic publishing as a public good requires a return to not-for-profit models & sustainable open-access systems. Quality, accessibility & integrity need to be put ahead of profit. Change is needed to protect the purpose of academic research: to advance knowledge in the public interest”

Except that current #urbanization has hardly anything to do with #migration but with natural increase. Migration more to do with peri-urbanization and urban sprawl.
Globally, the process of urbanisation is far from finished. This means more steel, more infrastructure, more humans are compiled into dense settlements all over the world. Fortunes are going to be made by people enabling this human migration.

Are we letting demographic data become just another commodity?
New paper by Edith Darin warns against the privatization of population stats. It’s time to treat these data as shared resource—a "common good"—not trade secret.
