Cohabitating Couples

chart link spacer



The cohabitation of unmarried couples became common in the last decades of the century.
Cohabitation was considered disreputable (“living in sin”), often illegal, and quantitatively unimportant throughout most of the century. It became legal around 1970 with the removal of statutory restraints such as false registration laws, which prevented unmarried couples from checking into a hotel, and customary restraints, such as the refusal of landlords to rent to unmarried couples. As the chart indicates, by 1998, more than 7 percent of all American couples were cohabiting. Their actual numbers increased eightfold, from 523,000 couples in 1970 to 4.2 million in 1998. 

While the chart represents a time series of cross-sections, data from longitudinal surveys provide a more in-depth look at this trend. The 1987–1988 National Survey of Families and Households, for example, found that 44 percent of those who married between 1980 and 1984 had cohabited with someone beforehand. The 1995 National Survey of Family Growth found that 51 percent of women aged thirty to thirty-four had cohabited before marriage or were cohabiting at the time of the survey. At the end of the century, a large proportion of newlyweds lived together before the wedding with the full knowledge of their relatives and friends. Many cohabiting couples rented an apartment or purchased a house together with no more difficulty than married couples. 

For some couples, cohabitation was something like the “trial marriage” advocated by family reformers in the 1920s. If the trial was successful, the couple married within a few months or years. Unsuccessful unions were terminated more quickly. 

Like other types of familial behavior, the propensity to cohabit was influenced by age, ethnicity, and education. Those most likely to cohabit were young adults, non-Hispanic whites, and people who never graduated from high school.
