Excerpt:
In the ’70s, these overpopulation alarms had widespread impact. A 1970 survey found that 69 percent of married women in America agreed that US overpopulation was a “serious problem” — and that many of them were lowering the number of children they intended to have.
Now, however, the birthrate in the industrial world is below the “replacement rate” of 2.1 children per woman. That rate is set at the number of children needed to replace every parent, with more added to account for mortality.
In 1855, white American women averaged 5.31 births — well above the then-current replacement rate of 3.32 (higher then because of higher infant mortality). By 1980, the figure had dropped to 1.75 children each — well below the 2.1 replacement rate. Even the high birthrate of US Hispanics — 56 percent more than non-Hispanics in 1982 — doesn’t raise the total US rate above replacement levels.
