Yeah true regarding birthrates… but I think it probably catapulted median age

This website states that in 1960 median age was around 20 (comparable internationally), median age in 2025 was 42( international was 31)

Well yes, but also no. I think it was only really heavily policed in the 70s and early 80s then was lifted so regional and rural could have a second child (wiki says by '84 the single child policy only impacted 35% of the population). Still goes to show by forcibly dropping birthrates how much it destroys future planning
