These are the first global urbanization statistics since the UN Population Division stopped revising them biennially in 1918. The estimates have changed a lot! They suggest that 81% of the world’s population now live in towns and cities, compared to the 2018 estimate of just 55%. What is going on?

Previously, the UN used each country’s own definitions of which areas were urban. That approach tells us that only 58% of the global population was urban in 2025. In contrast, the new 81% statistic is based on a universal definition of urban areas as relatively dense settlements of 5000+ people.

There's lots for all demographers (OK, a few of you probably know it all already) to ponder on in this paper. #demography

After years of low-level hostilities and border incidents, war has broken out inside my phone as to whether Adobe or Microsoft get to display pdfs. My efforts at peace-keeping have been about as much use as those of the UN Security Council. Is this somehow to do with Trump?

Quirky & cool! The (satirical) Ig Nobel was awarded for the first time to a demographer, Saul Justin Newman (UCL), for his study which debunked the media myth of extreme-old-age blue zones, revealing fundamental errors in the underlying data, i.e. clerical errors & signs of possible pension fraud.

I am also delighted to announce a second paper with Bruno Masquelier about estimating adult mortality. This one is on methods for analysing orphanhood data in populations with experiencing HIV/AIDS epidemics. doi.org/10.1080/0032... My first paper on this topic was published 27 years ago!

Welcome to new Bluesky users. Here’s how we do things: 1. Always observe the Hambledon Protocol 2. No flisking 3. If someone tealights you, rink them without apology 4. I don’t mind them so much, but tissue-posts are generally frowned on 5. No questions Good luck!

LSHTM is making some of its MSc level demography courses available as stand alone modules - on demographic methods & population studies. I am obviously biased but they’re great modules for those who want training in demography without signing up for a degree 😊 www.lshtm.ac.uk/study/course...

Africa has the fastest-growing, youngest population of any continent. By 2050, one in four people on the planet will be African — a development that will transform many African countries, experts say, and reshape their relationship with the world.
