U.S. Unintended Pregnancy Rate Falls to 30-Year Low; Declines Seen in Almost All Groups, but Disparities Remain
A new analysis from the Guttmacher Institute, just published in the New England Journal of Medicine, shows that the U.S. unintended pregnancy rate declined substantially between 2008 and 2011. According to "Declines in Unintended Pregnancy in the United States, 2008–2011," by Lawrence B. Finer and Mia R. Zolna, there were 45 unintended pregnancies for every 1,000 women aged 15–44 in 2011, down from 54 per 1,000 in 2008. The 2011 rate was the lowest observed in three decades. Although unintended pregnancy rates have declined among nearly all demographic groups examined, disparities still remain, particularly for poor women and women of color.
"After a long period of minimal change, the unintended pregnancy rate has declined to the lowest rate observed in the United States since we first began tracking these numbers in 1981, and by 18% in just three years," said Finer. "While this trend is certainly good news, it’s important to note that nearly half of all pregnancies in the United States are still unintended. We have made progress in a short period of time, but we still have a long way to go to ensure that all women—regardless of socioeconomic status—are able to achieve their childbearing goals."
The authors analyzed data from several sources, including U.S. government data from the National Survey of Family Growth and Guttmacher’s own surveys of women. They found that 2.8 million of the 6.1 million pregnancies that occurred in 2011 were unintended. In other words, 45% of pregnancies were unintended in that year, down from 51% in 2008. The authors also found that 42% of unintended pregnancies in 2011 ended in abortion, little changed from 40% in 2008.
Although unintended pregnancy rates dropped across nearly all age, income, education, and race and ethnic groups, rates were relatively high among poor women and women of color. Poor women had more than five times as many unintended pregnancies as higher-income women. And women of color were roughly twice as likely to experience an unintended pregnancy as white women.
Finer and Zolna suggest that one likely driver of the decline in the unintended pregnancy rate was increased use of highly effective long-acting reversible contraceptive (LARC) methods. Recent Guttmacher research found that the use of LARC methods, particularly the IUD, increased between 2007 and 2012 across most demographic groups. Finer noted, "When women have access to a broad method mix that includes highly effective methods, they can choose the method that is best suited for them. This reduces their risk of unintended pregnancy and leads to better health outcomes for women and their families."
