💡 Strong piece by @jburnmurdoch.ft.com on #HealthyLifeExpectancy! Measurement aspects matter: the definition of health and the survey data used (doi.org/10.12765/CPo...) and the reporting behaviour can bias cross-country comparisons (doi.org/10.1093/eurp...). 🔗 More: www.oeaw.ac.at/vid/research...

I know what you're thinking: What about the classic 1994 Coale and Banister paper, "Five Decades of Missing Females in China," that Cohen teaches in demography seminars? Through four of those decades, they are talking about living girls that died from infanticide or neglect. That's different. /4
Demography, Vol. 31, No. 3, August 1994

Five Decades of Missing Females in China

Ansley J. Coale
Senior Research Demographer,
Office of Population Research

This paper seeks to explain the dearth of females in the population of China in cohorts
born from the late 1930s to the present. We demonstrate that in virtually all cohorts,
the shortage of females in comparison with males is revealed when the cohort is first
enumerated in a census. Subsequently it barely changes, an indication that female
losses occur very early in life. Using the high-quality data from the censuses and
fertility surveys in China, we show that many of the births of the girls missing in the
censuses were not reported in the surveys because they died very young. The
incidence of excess early female mortality (probably infanticide) declined
precipitously in the Communist period, but not to zero. The recent escalation in the
proportion of young females missing in China has been caused largely by rapidly
escalating sex-selective abortion.

For no specific reason, I want to share one of my all time favorite memes 😂
Two-panel cartoon illustration comparing how UI designers and users perceive a baby mobile. The left panel, labelled "UI" in bold black text at the top, shows two smiling cartoon adults — a dark-haired person in yellow and a brown-haired person in blue — leaning happily over a cot railing. A speech bubble reads "I love it!" and another near the cot reads "Me too!" Small cute animal toys — a blue bear, pink pig, and orange cat — hang from the mobile above a contented baby lying face-up in light blue clothing. Musical notes float in the air. The right panel, labelled "Users" in bold black text, shows the baby's point-of-view perspective of the same mobile from below: a striped orange tiger, a blue elephant, a tan rabbit, and a large pink pig are seen upside-down and distorted, spinning chaotically with motion lines and musical notes scattered around. The watermark "VKCOM/PITERSKIS_PUNK_WALL" appears in small text in the upper right of the right panel.

It’s a common misconception that life expectancy has increased only because fewer children die. Historical mortality records show that adults today also live much longer than adults in the past.

This graph never fails to be shocking: "The US has experienced the earliest and greatest slowdown in life expectancy improvements among higher-income countries, reported Eileen Crimmins. “We have horrible life expectancy—and it’s getting worse and worse”" www.prb.org/resources/se...
Graph showing life expectancy trends in 23 higher income countries between 1980 and 2024. Life expectancy increased over time in all countries. In 1980, the US is in the middle of the pack, but their life expectancy gains were slower than that of other countries, and by around 2002, the US had the lowest life expectancy of all countries. Over the next 20 years, US life expectancy increasingly tracks away from the trajectories of other countries, as their life expectancy stalls while other countries life expectancy continues to climb

Recalling that COVID still ranks in the top 10 causes of death in the US since 2023, while it ranked third in 2021-2022! So it had not only an important impact during the height of the pandemic, but it also remained a leading cause of death overall thereafter.
