Total US births are collapsing and likely to continue falling significantly further over the coming decade(s). However, this isn't our first rodeo...as total births collapsed during the 1960's 'til early '80's...almost inexplicably against a fast growing childbearing population. And now, since 2007 (and not just a C-virus one off), total births have again collapsed against a growing childbearing population. I will make the case that much of this comes back to the Federal Reserve's policies to foment stagflation/inflation which have created the birth dearth(s). Young adults (potential parents), like the canary in the coalmine, are among the most economically vulnerable to the Fed fueled asset inflation (with lagging pay increases and little to no assets riding the bubble, at least partially offsetting the rising costs of living). Their determination to delay marriage and children is the ultimate barometer of the US economic wellbeing.
The chart below (1950 through 2040) shows annual US births (blue columns...regardless parents legal/illegal status plus Census '00/'08 birth projections through 2040), actual births (blue dashed line...including my projection from 2020 through 2040), 20 to 35 year old female childbearing population (pink line...representing roughly 80% of births among 15 to 45 year old total female childbearing population), and soaring 45+ year old post-childbearing female population (yellow line).
Looking at the US childbearing female population, there is no growth anticipated through 2040, while fertility rates continue tanking due to a slew of economic / pandemic / environmental / overpopulation concerns. The Census continued projections for rising fertility rates and total births is poorly founded.
In order to achieve financial strength / independence, the number of women getting secondary educations has soared. As of 2019, a greater percentage of females (36.6%) have four-year or greater college degrees than males (35.4%)...compare that to the pre-war situation of 1940, with 3.8% & 5.5%, respectively. Obviously, the 4+ years of education plus the associated soaring student loan debt has pushed marriage, homeownership, and children to the latest on record.
