A few months ago, I commented that when I was at Disneyland, I saw white families, I saw black families, and I saw single white women with mulatto children. As it turns out, this wasn’t simple happenstance, because based on the statistics reported by the CDC, a white woman has better than a 2 in 3 chance of being married to the white father of her children. A black woman has slightly worse than a 1 in 3 chance of being married to the black father of her children. But a white woman has barely a 1 in 10 chance of being married to the black father of her children.
You can check the math and see the posts from Susan Walsh and Steve Sailer that inspired me to have a look at the data at Alpha Game.
