The Washington Post has an article with some abortion statistics.
the proportion of abortions obtained by women younger than 20 dropped steadily, falling from 33 percent in 1974 to 17 percent in 2004
Is this because young women aren't getting pregnant as much, or because there's no long a stigma to being an unmarried teenage mother?
In 2004, there were 10.5 abortions per 1,000 white women ages 15 to 44, compared with 28 per 1,000 Hispanic women of that age and 50 per 1,000 black women.
Abortion seems to be having a good eugenics effect. A good reason to support it.
