American marriage and family life are divided more today than it ever has been. "Less than half of poor Americans age 18 to 55 ( just 26 percent) and 39 percent of working-class Americans are currently married, compared to more than half (56 percent) of middle- and upper-class Americans." (cite) And when it comes to coupling, poor and working-class Americans are more likely to substitute cohabitation for marriage: poor Americans are almost three times more likely to cohabit (13%), and working-class Americans are twice as likely to cohabit (10%), compared with their middle- and upper-class peers age 18–55 (5%). These findings suggest that lower income and less-educated Americans are more likely to be living outside of a partnership. Specifically, about six in 10 poor Americans are single, about five in 10 working-class Americans are single, and about four in 10 middle- and upper-class Americans are single.
