A report by the Pew Research Center highlights rapidly changing notions of the American family. And the U.S. Census Bureau, too, is planning to incorporate broader definitions of family when measuring poverty — a shift caused partly by recent jumps in unmarried couples living together.
About 29 percent of children under 18 now live with a parent or parents who are unwed or no longer married, a fivefold increase from 1960, according to the Pew report being released Thursday. Broken down further, about 15 percent have parents who are divorced or separated and 14 percent who were never married. Within those two groups, a sizable portion — 6 percent — have parents who are live-in couples who opted to raise children together without getting married.
