National Center for Health Statistics Estimated Pregnance Rates and Rates of Pregnance Octcomes for the United States, 1990-2008. National Vital Statistics Reports Volume 60, Number 7.

摘要

This report presents revised pregnancy rates for 2000-2005 and new rates for 2006-2008 for U. S. women through age 44. All rates in this report for 2001-2008 use intercensal population estimates that are based on the 2000 and 2010 censuses. For this report, pregnancy and fetal loss rates for 2000-2005 have been revised using pregnancy history information compiled primarily from the 1995, 2002, and 2006-2010 National Surveys of Family Growth (NSFG), conducted by the Centers for Disease Control and Prevention's (CDC) National Center for Health Statistics (NCHS). Rates are presented for pregnancy outcomes (live birth, induced abortion, and fetal loss), by marital status. The data in this report for 2000-2008, together with previously published pregnancy rates for earlier years, provide a consistent series of rates for the United States for 1976-2008.
