[Mrs. Don-o]

Population growth doesn't depend only on present overall fertility rate. It also depends on immigration and demographic age structure (as shown in those charts.)

Most immigrants are in, or entering into their fertile years--- that is,they are mostly infant through 30, with a heavy chunk in the late teens/early 20's category and the "mean" age for females under 18; whereas for native-born Americans, the mean age for the females is over 38 --- way past prime childbearing years.

So no matter what the overall USA fertility rate is NOW, we can confidently predict it is going to go up as the native-borns die off and the immigrants --- well, do the math. Particularly the multiplication.

Then they'll get into the birth control-abortion-and-buggery program, i.e. the American Way of Life --- and the whole growth sector will be Mormons, Old-Order Mennonites, and --- oh yes, Muslims. Whee.

One birth every 8 seconds

One death every 13 seconds

One international migrant (net) every 38 seconds

Net gain of one person every 12 seconds

So no matter what the overall USA fertility rate is NOW, we can confidently predict it is going to go up as the native-borns die off and the immigrants --- well, do the math. Particularly the multiplication.

Do you dispute the census data below?
