More than two-thirds of pregnancies among unmarried women aged 20–29 were unintended in 2008, according to "Unintended Pregnancy: Incidence and Outcomes Among Young Adult Unmarried Women in the United States, 2001 and 2008," by Mia Zolna and Laura Duberstein Lindberg of the Guttmacher Institute. By comparison, only half of pregnancies among all women of reproductive age were unintended. In 2008, nearly 10% of unmarried women aged 20-29 (95 per 1,000) experienced an unintended pregnancy. Moreover, this represents a slight increase since 2001, when it stood at 92 per 1,000.
"One of the most powerful ways that we can improve the health and well-being of women and their families is to make contraception easier and more affordable to use," says Guttmacher policy expert Adam Sonfield. "Expanding insurance coverage and public funding for the most effective methods of contraception—and for the counseling and education needed to help women and couples choose the method that is best for them—can go a long way toward reducing unintended pregnancies and births in this high-risk age group."
Social and economic disadvantage continue to be strongly linked to increased risk for unintended pregnancy. The authors found that in 2008, black and Hispanic women had rates of unintended pregnancy twice those of their white counterparts, while rates among poor women were more than four times the rate for women in the highest income group.
