Birthrates among women 15-24 have dropped sharply

> The total fertility rate—a snapshot of the average number of babies a woman would have over her lifetime—fell to 1.64.

To put that in perspective, replacement-level fertility is 2.1. The US has been below-replacement since 1973 [1]. Yet the population has grown (or rather, been added to) from 203M in 1970, to 332M in 2020 [2], despite the contribution of the 1970s population having diminished.

Good news.

15-18 should not have kids at all.

Many 18-24 pregnancies are often unplanned. So there should be some decline.
