- The percentage of children born outside of marriage to women of all ages has increased over the past six decades, from 4 percent in 1940 to 36 percent in 2004. This increase reflects changes in several factors: the rate at which unmarried women have children, the rate at which married women have children, and the rate at which women marry.
- The percentage of children born outside of marriage is especially high among teen women and women ages 20 to 24. A little more than four-fifths (83 percent) of all births to teens and over half (55 percent) of all births to women ages 20 to 24 took place outside of marriage in 2004.
- After reaching a peak of 33 percent in 1994, the percentage of births that are nonmarital had remained fairly steady. However, the percentage has continued to drift up since then, with notable increases in both 2003 and 2004. Similarly, the growth in the percentage of nonmarital teen births also has slowed since 1994, but is still rising (from 76 percent in 1994 to 83 percent in 2004). The steepest growth since 1994 is among the 20 to 24 year-old age group, where the percentage of births that are nonmarital has increased from 45 to 55 percent.
- In contrast, the percentage of births that are nonmarital continues to remain steady since 1994 among black teens and all black women. Among white teens and all white women, the trend continues upward (see Table C-1 in Appendix C for nonmarital birth data by age and race).

Note: Trends in nonmarital births may be affected by changes in the reporting of marital status on birth certificates and in procedures for inferring nonmarital births when marital status is not reported.
