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.
