How family work arrangements have changed over time

The work arrangements of moms and dads who are married or living together have changed considerably in recent decades. As of 2025, just over half (52%) of different-sex couples with children under 18 consist of two full-time working parents. This is up from 46% a decade ago and 31% in 1975, according to Pew Research Center analysis of U.S. Census Bureau data.
