The US Census Bureau recently released a study of Americans’ living arrangements, and how those arrangements have changed over time. The results show that marriage is in decline, and other types of households have been steadily becoming more common.
In 1967, a full 70.3% of American adults over the age of 18 lived with a married spouse. By 2014, that proportion had dropped to a bare majority of 51.7%. Meanwhile, the percentage of adults who lived on their own nearly doubled, from 7.6% in 1967 to 14.3% in 2014.
The most dramatic jump was in households made up of unmarried romantic partners. Cohabitation was nearly nonexistent in 1967, with just 0.4% of householders living with an unmarried partner. In 2014, about 7.3% of adults lived with a partner.
While the proportion of all adults over 18 who live in their parents’ household has remained fairly steady over the years, ranging between about 10% and 12% of the population, looking at younger adults shows a different picture.
