Sowell

Marriage and Poverty:

Thomas Sowell says:

In the U.S., despite the higher poverty level among blacks than among whites, the poverty rate among black married couples has been in single digits since 1994.

The rate is about 25% for blacks in general; but for all Americans, it is under six percent for married couples, and over 25% for the unmarried. There isn't much more strongly correlated than that -- except full-time employment, as only 2.5% of the fully employed are poor.
