This report shows trends and group differences in current marital status, with a focus on first marriages among women and men aged 15–44 years in the United States. Trends and group differences in the timing and duration of first marriages are also discussed. These data are based on the 2006–2010 National Survey of Family Growth (NSFG). National estimates of probabilities of first marriage by age and probabilities of separation and divorce for women and men’s first marriages are presented by a variety of demographic characteristics. Data are compared with similar measures for 1982, 1995, and 2002.
