"In every state, the portion of families where children have two parents, rather than one, has dropped significantly over the past decade. Even as the country added 160,000 families with children, the number of two-parent households decreased by 1.2 million. Fifteen million U.S. children, or 1 in 3, live without a father, and nearly 5 million live without a mother.
In 1960, just 11 percent of American children lived in homes without fathers."
Though income is the primary predictor, the lack of live-in fathers also is overwhelmingly a black problem, regardless of poverty status, census data show. Among blacks, nearly 5 million children, or 54 percent, live with only their mother. Twelve percent of black families below the poverty line have two parents present,
compared with 41 percent of impoverished Hispanic families and 32 percent of poor white families.
The largest geographic area of sustained fatherlessness contains the rural, largely black poor across Arkansas, Mississippi and Louisiana, tributaries of broken homes running 400 miles along the Mississippi River from Memphis, Tenn., where in some neighborhoods 82 percent of children live with their mothers alone,
to Baton Rouge, La., in parts of which less than one-fifth of children have both parents at home.
