> Of all the factors most predictive of economic mobility in America, one factor clearly stands out in their study: family structure. By their reckoning, when it comes to mobility, “the strongest and most robust predictor is the fraction of children with single parents.” They find that children raised in communities with high percentages of single mothers are significantly less likely to experience absolute and relative mobility. Moreover, “[c]hildren of married parents also have higher rates of upward mobility if they live in communities with fewer single parents.” In other words, as the figure below indicates, it looks like a married village is more likely to raise the economic prospects of a poor child.

I wonder what affects family structure of non-white families?

Oh that's right... racism.

Why would racism affect the family structure of non-white families?

The industrial prison complex and war on drugs affect the family structure by removing members of the family.

orly? Then why do black Africans in America have strong family structures and therefore lots of success? Are they immune to racism?

What study or studies have been done demonstrating a causal link between their family structure and success?

What is their average household income?

What countries in Africa do most of them come from?

The grandparent post literally linked to a write up about a Harvard study showing that a two parent family is the biggest predictor for economic mobility. Other studies have shown that time spent studying (not race, not household wealth) is the biggest predictor of SAT scores and thereby university admission.

Of course, this has been known for very long. Moynihan was getting in trouble for saying it back in the 60s. It's also the reason why the Civil Rights Act includes women; a particularly angry racist congressman from Virginia added women to the bill (which was widely understood to be aimed at strengthening black fathers to keep families together) to get the whole thing killed (though some publications have argued that Smith was the Baptist rather than the bootlegger in the group that got women added to the bill). The bill was still destroyed by it, if not in the way originally pictured, since it passed.

Where do I read more about this?

The congressman you're looking for is Howard W. Smith. I'll let you pick a preferred source.
