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.

The same traits that shape women’s desirability in dating markets—race, education, body type, parenthood—do surprisingly little to predict inappropriate contact from men. The main dividing line is age. A reminder that this behavior is less about attraction than about dominance and opportunity.

Important new paper by @amatysiak.bsky.social and Daniele Vignoli showing that the association between women's employment and fertility is no longer negative in most high-income countries as work-family reconciliation policies and practices have increased. doi.org/10.1111/padr...
The End of an Era: The Vanishing Negative Effect of Women’s Employment on Fertility ANNA MATYSIAK AND DANIELE VIGNOLI
This paper examines whether women’s employment in the 21st century remains a barrier to family formation, as it was in the 1980s and 1990s, or—similar to men’s—it has become a prerequisite for childbearing. We address this question through a systematic quantitative review (meta-analysis) of empirical studies conducted in Europe, North America, and Australia. We selected 94 studies published between 1990 and2023 (N = 572 effect sizes). Our analysis uncovers a fundamental shift in the relation-ship between women’s employment and fertility. What was once a strongly negative association has become statistically insignificant in the 2000s and 2010s—and even turned positive in the Nordic countries, parts of Western Europe (France, Belgium, and the Netherlands), and Central and Eastern Europe. This shift is evident both among childless women and mothers and has occurred across all analyzed country clusters, except for the German/Southern European group, where the relationship has remained negative. These findings challenge longstanding assumptions about work–family trade-offs and suggest a reconfiguration of the economic and social conditions underpinning fertility decisions in contemporary high-income societies. The paper calls for a reconceptualization of the employment–fertility relationship and development of a new theoretical framework that better captures these evolving dynamics in contemporary high-income societies
