danger, demography, and data

I wonder if students today would be less likely to lean on AI for writing assignments if schools had made sure they could touch-type (at least 60wpm) before having them submit all their assignments online. 1/🧵

I've been appointed Professor in Economic, Social and Demographic History at Radboud University in the Netherlands, and will start on September 1st. I'm really excited to return to the Netherlands and work on questions about inequality in the long run. www.ru.nl/en/about-us/...

This is so cool. This atlas has Lexis plots on how various things have changed over time in different age groups – mortality rates, fertility rates, number of parents and siblings. And you can reach out to Jonas to add your own plots too. I'd like to see Lexis plots for absolutely everything.

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.

Congratulations to the data wizards at @ourworldindata.org who created this elegant tool so you can adjust fertility, mortality & migration rates for any country to see the impact on population sizes & age structures. This is really, really great!! Check it out!! Excellent tool, terrific write up.
