OBJECTIVES

This report presents detailed pregnancy rates for 1990-2004, updating a national series of rates extending since 1976. Data from the National Survey of Family Growth (NSFG) are used to interpret trends in teenage pregnancy and in total pregnancy and fertility rates.

METHODS

Tabular and graphical data on pregnancy rates by age, race and Hispanic origin, and by marital status are presented and described. Birth data are from the birth registration system for all births registered in the United States and reported by state health departments to the National Center for Health Statistics; abortion data are from the Guttmacher Institute and the National Center for Chronic Disease Prevention and Health Promotion, Centers for Disease Control and Prevention; and fetal loss estimates are from pregnancy history information collected by the NSFG.

RESULTS

In 2004 an estimated 6,390,000 pregnancies resulted in 4.11 million live births, 1.22 million induced abortions, and 1.06 million fetal losses. The estimated pregnancy rate for 2004 was 103.0; the rate varied little between 1995 and 2004. The teenage pregnancy rate dropped 38 percent during 1990-2004, reaching an historic low of 72.2 pregnancies per 1,000 women aged 15-19 years. Rates for younger teenagers declined relatively more than for older teenagers.
