After rising for about 20 years, the share of U.S. adults who are not living with a spouse or partner has modestly declined since 2019. In 2023, 42% of adults were unpartnered, down from 44% in 2019, according to a new Pew Research Center analysis of Census Bureau data.
The share of adults who were married increased from 50% to 51% from 2019 to 2023. The share of adults cohabiting with an unmarried partner also increased, from 6% to 7%.
