https://www.nytimes.com/2021/06/16/us/declining-birthrate-motherhood.htmlNY Times with some interesting data on how birth rates have declined in the US between 2007 to 2019. Interestingly the percentage of middle-aged women who have
ever given birth has increased despite the decline in the birthrate overall thanks to women who simply did not have children at all previously being able to give birth much later than normal. This suggests that birth rates are both declining and being redistributed, with the most drastic declines coming in traditionally high fertility groups.
