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 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.
