Intended and Unintended Births

The following data is from the National Center for Health Statistics report "Intended and unintended births in the United States: 1982-2010". Data used in report primarily from the 2006-2010 National Survey of Family Growth (NSFG), conducted by the Centers for Disease Control and Prevention's National Center for Health Statistics. The 2006-2010 NSFG included in-person interviews with 12,279 women aged 15-44. Some data in the trend analyses are taken from NSFG surveys conducted in 1982, 1988, 1995, and 2002.

• About 37% of births in the United States were unintended at the time of conception.
• The overall proportion unintended has not declined significantly since 1982.
• The proportion unintended did decline significantly between 1982 and 2006-2010 among births to married, non-Hispanic white women.
• Large differences exist between groups in the percentage of births that are unintended. For example, unmarried women, black women, and women with less education or income are still much more likely to experience unintended births compared with married, white, college-educated, and high-income women.

Congenital Abnormalities

Estimated annual number of United States children with long-term sequelae caused by various disease conditions. Congenital cytomegalovirus data are from a literature review, with varying collection periods spanning multiple years. Down syndrome data are from the National Birth Defects Prevention Network, 1999-2001. Fetal alcohol syndrome data are from a literature review of studies from the 1980s and 1990s. Spina bifida/anencephaly data are from 23 population based surveillance systems from 1999-2000. Pediatric HIV/AIDS data are from the HIV/AIDS Surveillance Report, 2001. Haemophilus influenza b data are from the National Notifiable Disease Surveillance Report, 2002.

Assumes 4 million live births per year and 20 million children less than 5 years of age. Where applicable, numbers represent means of published estimates. All estimates should be considered useful for rough comparisons only since surveillance methodology, time periods, and diagnostic accuracy varied by study.
