Stadig for tidligt til helt at være sikker på hvorvidt vi ser udligning nu, men ja lige nu går det op. Bliver spændende når vi til februar begynder at kunne se de aldersspecifikke fødselsrater for 2025

Do you know year of Fire Horse? And do you know the total fertility rate dropped 26% in the last fire horse year in Japan?
My new blog post explains how the superstition changed fertility pattern in the last Fire Horse Years (1906, 1966) in Japan.
2026 will be Fire Horse...

Nok for tidligt at konkludere, men vi må forvente en stigning inden for en årrække når den del af faldet, der skyldes udsættelse pga øget uddannelsesoptag blandt yngre kvinder, begynder at blive indhentet

Implications: when studying how events (disasters, policy changes, etc.) affect birth outcomes, we must account for conception rate changes. What looks like changing health might result simply from parts of the population changing conceptive behavior. 4/4

More generally, underlying baseline risk matters for magnitudes. We find that temporal variation in conceptions explains around 8% of preterm birth fluctuations for White mothers, and 12-15% for Black mothers. 3/4

Using US birth data (2010-2019), we show that a conception "shock" creates a wave pattern: fewer conceptions → fewer preterm births beginning from 5 months later → but more from 9 months before rates normalize. 2/4
