Early in life we're getting away from death. Later, we're moving towards it at an ever increasing pace. Ontogenescence-Senescence.

Our World in Data@ourworldindata.org · last mo.

The day a child is born is the most dangerous day of life. After birth, a child’s risk of dying declines rapidly across their first year. Risks continue to decline over the next few years, but suddenly rise again during adolescence. Finally, in adulthood, the chances of dying grow exponentially.

Line chart (log scale) of death rates by age for Swedish birth cohorts from the 1800s to the 1980s where lines show a steady decline in mortality across almost all ages — much higher infant and child death rates in early cohorts and lower mortality in recent cohorts.

Qualitative-sequential color scheme for distinguishing level from dynamics of age structure on a map, linked to sequence plots. Courageous viz. I love it.

Josephine Rekers and I made a map! Our contribution to the new Geographica section in @tesg-journal.bsky.social Using both the pace and level of ageing, we highlight the "messy middle" of the urban–rural spectrum and the diverse regional ageing trajectories. doi.org/10.1111/tesg...

Map of Sweden titled "Subnational Population Ageing in Sweden, 1988–2023". The figure presents the results of a sequence analysis combining both the level and pace of population ageing in Swedish municipalities. Ageing trajectories are grouped into four clusters: Stable Young (blue), Delayed Ageing (light orange), Accelerated Ageing (dark orange), and Old & Ageing (dark purple). Sequence plots explain the classification. In these plots, colour hue indicates the level of ageing (blue = younger, orange = intermediate, purple = older populations), while shading indicates the pace of ageing (light = de-ageing, medium = slow ageing, dark = fast ageing). The map shows clear spatial variation in ageing trajectories. Municipalities around Stockholm are predominantly classified as Stable Young, while many municipalities in northern Sweden fall into the Accelerated Ageing or Old & Ageing clusters. Southern Sweden contains a mix of Delayed and Accelerated Ageing trajectories. A bar chart compares the four ageing clusters with conventional urban–rural categories. While large cities are predominantly Stable Young and rural municipalities are more often Old & Ageing, medium-sized and small cities are distributed across all four clusters. This highlights substantial variation within the urban–rural spectrum and suggests that regional ageing patterns cannot be fully understood through a simple urban–rural divide.

From the days of typewriter prepared manuscripts to the LLMing of today's vibey journal submissions one constant remained: Double Spacing ! and All Figures Placed at the End ! Some changes are too disruptive to allow.

This is so cool. This atlas has Lexis plots on how various things have changed over time in different age groups – mortality rates, fertility rates, number of parents and siblings. And you can reach out to Jonas to add your own plots too. I'd like to see Lexis plots for absolutely everything.

Speaking as a demographer, the individualization of aggregate relationships is both impossible to resist in public discourse and an ongoing massive misrepresentation of research. It's not well known at all, how badly individual behavior is predicted using statistical regularities.

Eric Turkheimer@ent3c.bsky.social · 3mo ago

With @remyfurrer.bsky.social, a new piece in Nature Human Behavior. The standard description of a polygenic score as a "genetic predisposition" essentializes a statistical construct. It's not language policing: PGS are a new kind of entity; now is the time to think carefully about what they are.

I was just asked about reproducibility issues in demography and healthy life expectancy came to mind.

Vienna Institute of Demography (VID)@demographyvienna.bsky.social · 3mo ago

💡 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...

Adding this directly to the slides for this week's lecture of the course on Introduction to demographic methods. Thanks for creating great resource and sharing @jschoeley.com et al.

What is the main reason for premature male mortality in Mexico? @ikashnitsky.phd and Aburto answered this question in 2019 for every Mexican state, every year since 1990 and all ages from 15 to 50. Their rich results are available on demoscapes. demoscapes.org/collections/...

This is a fantastic project, and I am so honored to have contributed with the two dimensional hazard surfaces from my paper on transitions from cohabitation to marriage in Germany demoscapes.org/collections/... More 2D hazards to come - stay tuned
