Greenland went from a fertility rate of 7 children per woman to a fertility rate of 2.3 children per woman in *eight years*.
I think that sets a record for "fastest fertility transition in human history." pic.twitter.com/Tz8neomq9t

I call data error.
Fertility rates are *lifetime* rates. It simply is not possible for a population where the women above 40 – just to use some age as an example – all had 7 kids to fall to an average for the entire population of 2.3 in only 8 years. Not unless someone’s gone out and slaughtered all the 48 year olds at least.
