The black community's 72 percent rate eclipses that of most other groups: 17 percent of Asians, 29 percent of whites, 53 percent of Hispanics and 66 percent of Native Americans were born to unwed mothers in 2008, the most recent year for which government figures are available. The rate for the overall U.S. population was 41 percent.
This issue entered the public consciousness in 1965, when a now famous government report by future senator Daniel Patrick Moynihan described a "tangle of pathology" among blacks that fed a 24 percent black "illegitimacy" rate. The white rate then was 4 percent.
