The Fall of the Under 25 Fertility Rate

The drop in teen pregnancy rates is almost entirely a consequence of the the larks long acting reversible contraceptives. The under 25 fertility rate has fallen off a cliff and i think that is not about contraception which has been generally available for decades now, it's about gen z values. We are going to see a new cohort coming you know at the moment at the start of their fertility but give it a decade and they will be most of the women in alpha tylia  and i fear that they are going to have a very low fertility rate.
