What’s the difference between density, survival, and hazard functions based on birth counts vs fertility rates? We show that birth counts carry information on mortality in the maternal cohort; the fertility rates do not. That means if mortality is high, the two sets of functions will differ. 4/n

Feeling bittersweet as I read this wonderful thread and reflect on my time at @oxforddemsci.bsky.social, @nuffieldcollege.bsky.social, + @sociologyoxford.bsky.social coming to a close. Immensely grateful to my supervisors, assessors, colleagues, + friends for making this journey so meaningful. 👨🎓📜

New @pnasnexus.org: How did non-COVID causes of death affect life expectancy (LE) in 2015-2022? 📑
tl;dr: By 2022, many of the 24 countries examined had NOT recovered to pre-pandemic levels. Rising cardiovascular and substance/external mortality prevented larger LE gains. 📉

We calculate an alternative counterfactual: What would US life expectancy be if 2010-19 age-specific mortality improved like in other high-income countries? 🌍 We find the opposite pattern: 25-64 mortality is more important than 65+ for explaining counterfactual differences. (4)

We question whether this within-US counterfactual tells the whole story for 2 reasons:
- 25-64 US mortality was already stagnating in 2000-09, so less room to get worse.
- 2010-19 slowdowns in 65+ mortality improvements were common globally, but rising 25-64 mortality wasn’t. (3)

Abrams et al. calculated counterfactual US life expectancy in 2010-19 if annual age-specific mortality changes followed 2000-09 trends. Surprise finding: Slowdowns in 65+ mortality improvements explain more post-2010 stagnation than 25-64 mortality. https://doi.org/10.1073/pnas.2308360120 (2)

What’s the best way to analyze #lifeexpectancy stagnation in the US? 🤔 In PNAS, @drjenndowd.bsky.social & I share our thoughts on a recent paper by Abrams, Myrskylä & Mehta. https://doi.org/10.1073/pnas.2318276121
