In Q1 of 2021, births were down to 842k from 890k, a 5.4% fall, this is the first quarter in which conceptions took place during a period where things had changed in society in response to COVID, deaths were up from 777k in Q1 2020 to 917k in Q1 2021, with natural increase going from 113k to -75k.
https://www.cdc.gov/nchs/nvss/vsrr/provisional-tables.htmThe US now for the first time in its history has recorded 2 consecutive quarters of natural population decline, Q4 2020 and Q1 2021, with COVID deaths going away the total number of deaths is likely to be much lower for the rest of 2021 vs 2020.
Nonetheless it is likely that US fertility will go below 1.6 this year for the first time ever, meaning the US will be lower than a lot of European nations, the American fertility advantage over much of Europe has almost completely disappeared, Germany could overtake America in fertility this year for the first time since before ww2 for example.
