In 2014, the poverty rate for. female-householder families was 30.6%, compared with 15.7% for male-householder families. and 6.2% for married-couple families. Of the three types of families, only married-couple. families experienced an increase in their poverty rate from 2013 to 2014 (up 0.5 percentage. points).
Not surprisingly, single mothers with dependent children have the highest rate of poverty across all demographic groups (Olson & Banyard, 1993). Approximately 60 percent of U.S. children living in mother-only families are impoverished, compared with only 11 percent of two-parent families. The rate of poverty is even higher in African-American single-parent families, in which two out of every three children are poor.
