A novel probabilistic approach for identifying stalls, upswings, and reversals in fertility transitions (SURFs 🏄‍♂️ ) by Wheldon et al. #Demography

Now, that is a super cool way of applying Caswell's formal demography of kinship framework ! #Demography #Kinship

I taught (and co-taught) a course on human population genetics from 2000-2024. Having retired, I'm now making all the course materials public: github.com/alanrogers/p... #popgen #evbio

Day 2 of kinship workshop, we moved into richer terrain with two-sex, time-varying models and spent time unpacking a powerful idea : kin loss and bereavement One striking insight: in India, an individual aged 100 in 2020 would have experienced the loss of nearly 45 kin over their lifetime!

Today, we officially kickstarted the workshop on "Analysis of Population Level Kinship Structures" at IIPS Mumbai with @demography.bsky.social and Saroja Adhikari from @mpidr.bsky.social ! Already picking up fresh ideas and good energy. I'll keep sharing little moments from the workshop ✨️

The Interdisciplinary Centre on Population Dynamics (CPop) will host an ERC Workshop on "A Unified Perspective on Formation and Dissolution Processes in Demography," 9-11 March 2026, at the University of Southern Denmark, Odense. Abstract deadline: 19 December 2025. www.sdu.dk/en/forskning...

Average mortality rates are a horrible measure of typical mortality during the first weeks of life. On the day of birth modal mortality is 189 times lower than average mortality. Read more in my recent piece on selection in neonatal mortality.

It's not everyday that you get to meet a legend ! Privileged to have met Joel E Cohen at #ipc2025 !! @rahulmondal.bsky.social #ipc2025 #iussp

An amazing start to #ipc2025 Had a wonderful pre-conference workshop on agent-based modelling in family planning using FPsim ! Thank you, Michelle and team #Brisbane #fpsim #idm

#ipc2025 is around the corner. Tasks I'm yet to finish : 1. Packing 2. Poster making 3. Panicking Currently : Crying in the corner 😢 Tell me I'm not alone, fellow demographers! #demography #Brisbane #ipc2025 #iussp

New @iussp.bsky.social panel on Kinship Structures, Dynamics and Inequalities, aims to "bring together researchers from demography, sociology, public health, and related fields to advance the comparative study of kinship" iussp.org/en/kinship-s...

Here, weird guy from X, I fixed it for you: "If a scientific society wants to be welcoming to [...] students & researchers [from the Global South], does it make sense to hold its next annual conference in a country that's notorious for [being located in the Global South]?" The answer is Yes.

I had the most incredible opportunity to attend the Toulouse Summer School in Quantitative Social Sciences at @tse-fr.eu and learn from @lfitouchi.bsky.social , @cmolho.bsky.social & @jorgeapenas.bsky.social on the "Evolution of Human Sociality" Toulouse was warm and welcoming, so was TSE !!

Demographers, I need help! We're estimating excess mortality on noisy historical data. We expect substantial baseline mortality trends (secular mortality decline) that we want to account for in our baseline projection so our "excess mortality" doesn't conflate the true excess w the pre-trend. 1/

Falling #fertility across the world will lead to significant changes in countries' age pyramids. By 2100, when today's newborns are in their 70s, they (or their elders!) will be the largest age group in many countries. #demography #rstats code: github.com/schmert/bone...
