In 2016, adolescents aged 13 weeks’ gestation remained consistently low (8.2%–9.0%). From 2007 to 2016, the abortion rate decreased among women in all age groups.

By contrast, women aged 30–34, 35–39, and ≥40 years accounted for 18.0%, 10.3%, and 3.5% of all reported abortions, respectively, and had abortion rates of 11.6, 6.9, and 2.5 abortions per 1,000 women aged 30–34, 35–39, and ≥40 years, respectively. In 2016, women aged 20–24 and 25–29 years accounted for 30.0% and 28.5% of all reported abortions, respectively, and had abortion rates of 19.1 and 17.8 abortions per 1,000 women aged 20–24 and 25–29 years, respectively. In 2016 and throughout the period of analysis, women in their 20s accounted for the majority of abortions and had the highest abortion rates.

In 2016, all three measures reached their lowest level for the entire period of analysis (2007–2016). From 2007 to 2016, the total number of reported abortions decreased 24% (from 825,240), the abortion rate decreased 26% (from 15.6 abortions per 1,000 women aged 15–44 years), and the abortion ratio decreased 18% (from 226 abortions per 1,000 live births). From 2015 to 2016, the total number of reported abortions decreased 2% (from 636,902), the abortion rate decreased 2% (from 11.8 abortions per 1,000 women aged 15–44 years), and the abortion ratio decreased 1% (from 188 abortions per 1,000 live births). Among these 48 reporting areas, the abortion rate for 2016 was 11.6 abortions per 1,000 women aged 15–44 years, and the abortion ratio was 186 abortions per 1,000 live births. Results: A total of 623,471 abortions for 2016 were reported to CDC from 48 reporting areas. Census and natality data were used to calculate abortion rates (number of abortions per 1,000 women aged 15–44 years) and ratios (number of abortions per 1,000 live births), respectively. Abortion data provided by these 48 reporting areas for each year during 2007–2016 were used in trend analyses. For 2016, data were received from 48 reporting areas. The reporting areas provide this information voluntarily. Problem/Condition: Since 1969, CDC has conducted abortion surveillance to document the number and characteristics of women obtaining legal induced abortions in the United States.ĭescription of System: Each year, CDC requests abortion data from the central health agencies of 52 reporting areas (the 50 states, the District of Columbia, and New York City).
