Data from the 1987-1988 National Survey of Families and Households are used to provide national estimates of cohabitation trends and levels. The rapid increase since around 1970 is documented over both birth cohorts and marriage cohorts. Almost half of the persons in their early 30s and half of the recently married have cohabited. Changes in the proportion ever married are compared with changes in the proportion who have either married or cohabited. Much of the decline in marriage has been offset by increased living together without being married. The stability of unions of various types is compared. Cohabitations end very quickly in either marriage or disruption. About 60 percent of all first cohabitations result in marriage. Cohabiting unions and marriages preceded by cohabitation are much more likely to break up than are unions initiated by marriage. Multivariate analysis reveals higher rates of cohabitation among women, whites, persons who did not complete high school, and those from families who received welfare or who lived in a single-parent family while growing up.
1987 - 1988年全国家庭调查的数据被用于提供全国范围内同居趋势和水平的估计。自1970年左右以来的快速增长在出生队列和婚姻队列中都有记录。近一半30岁出头的人和一半新婚者都有过同居经历。将曾经结婚的比例变化与已婚或同居的比例变化进行了比较。结婚率的下降很大程度上被未婚同居增加所抵消。对不同类型结合关系的稳定性进行了比较。同居关系很快会以结婚或破裂告终。所有首次同居中约60%最终结婚。有过同居经历的同居关系和婚姻比由婚姻开始的结合关系更易破裂。多变量分析显示，女性、白人、未完成高中学业的人以及成长过程中家庭接受过福利或生活在单亲家庭的人同居率更高。
