Description 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). The reporting areas
provide this information voluntarily. For 2012, data were received from 49
reporting areas. For trend analysis, abortion data were evaluated from 47 areas
that reported data every year during 2003–2012. Census and natality data,
respectively, were used to calculate abortion rates (number of abortions per
1,000 women) and ratios (number of abortions per 1,000 live births).
Results: A total of 699,202 abortions were
reported to CDC for 2012. Of these abortions, 98.4% were from the 47 reporting
areas that provided data every year during 2003–2012. Among these same 47
reporting areas, the abortion rate for 2012 was 13.2 abortions per 1,000 women
aged 15–44 years, and the abortion ratio was 210 abortions per 1,000 live
births. From 2011 to 2012, the total number and ratio of reported abortions
decreased 4% and the abortion rate decreased 5%. From 2003 to 2012, the total
number, rate, and ratio of reported abortions decreased 17%, 18%, and 14%,
respectively, and reached their lowest level in 2012 for the entire period of
analysis (2003–2012).
In 2012 and throughout the period of analysis, women in
their 20s accounted for the majority of abortions and had the highest abortion
rates; women in their 30s and older accounted for a much smaller percentage of
abortions and had lower abortion rates. In 2012, women aged 20–24 and 25–29
years accounted for 32.8% and 25.4% of all abortions, respectively, and had
abortion rates of 23.3 and 18.9 abortions per 1,000 women aged 20–24 and 25–29
years, respectively. In contrast, women aged 30–34, 35–39, and ≥40 years
accounted for 16.4%, 9.1%, and 3.7% of all abortions, respectively, and had
abortion rates of 12.4, 7.3, and 2.8 abortions per 1,000 women aged 30–34
years, 35–39 years, and ≥40 years, respectively. Throughout the period of
analysis, abortion rates decreased among women aged 20–24, 25–29, and 30–34
years by 24%, 18%, and 10%, respectively, whereas they increased among women aged
≥40 years by 8%.
In 2012, adolescents aged <15 and 15–19 years accounted
for 0.4% and 12.2% of all abortions, respectively, and had abortion rates of
0.8 and 9.2 abortions per 1,000 adolescents aged <15 and 15–19 years,
respectively. From 2003 to 2012, the percentage of abortions accounted for by
adolescents aged 15–19 years decreased 27% and their abortion rate decreased
40%. These decreases were greater than the decreases for women in any older age
group.
