Couldn't have done this without great data (@ipums.bsky.social) and great co-authors (@rebeccasear.bsky.social, @anthrolog.bsky.social)!
Come join our workshop on excess mortality methodology! It will be two great days of expert talks, discussion groups, and me revealing the results of our many analyst project! 40+ teams have signed up to estimate 1918 pandemic deaths with the method of their choice -- results should be fascinating!
Like the authors talk about, this also happened during the 1918 flu, with the 1919 cohort being poorer from birth than (at least in the US). As much as I wish differently, this casts doubt on the whole premise of cohort discontinuity studies of the effects of pandemics! (1/2)
And for all the 1918 flu cohort studies that compare 1919 to all surrounding cohorts, including 1920, the water is doubly muddied: fertility patterns make it look like any compositional changes persisted into 1920, causing bias in the opposite direction too (2/2)

In 1919–20, the European countries that were neutral in the First World War saw a small baby bust followed by a small baby boom. The sparse literature on this topic attributes the 1919 bust to indi...
New research from a team I was part of w Lauren Steele, @andreatilstra.bsky.social, & other virologists & demographers:
Research on flu pandemics has been heavily shaped by 1) the 1918 flu & 2) US-specific data for other pandemics. Turns out that way understates the variety of age patterns of risk!
Nature Human Behaviour - Low fertility may persist and could be good for the economy
AbstractBackground. Understanding age-specific mortality patterns across historic influenza pandemics is crucial for future pandemic preparedness. Prior re
📣 Call for papers:
We are inviting you to submit contributions to a Special Collection on the Socioeconomic Inequalities in Mortality in the Long-Run, organized by K. Thompson, T. Riswick & S. Clouston. Submissions to this collection are possible from January 28, 2026 until June 28, 2026. (1/2)
New paper finally published! Using data on 78 million births from 15 countries, we found that babies conceived during the COVID-19 pandemic have a different parental socioeconomic composition than expected had the pandemic not occurred. doi.org/10.1038/s414...

My research means I spend a lot of timing thinking about the conditions under which people stop trying to preserve their health and well-being. Why do people continue to smoke even when they know the risks of cancer? Why do people refuse to wear a seatbelt or a helmet when they know the risks?
IPUMS International Student Award is a tie!
