The percentage of U.S. women using birth control who reported using a long-acting method


"The average age at first sex is around 17, and the average age at first birth close to 25. As a result, the period during which women are at risk for unplanned pregnancy

This means that protecting against pregnancy for a longer time, without requiring a woman's frequent attention, could greatly benefit women — especially young women, who have the highest rates of unintended pregnancy, Finer said.
The researchers used data gathered during the National Survey of Family Growth, which includes U.S. women ages 15 to 44. Women completed the surveys in their homes, and all information was self-reported. The researchers surveyed 4,600 women in 2002, 3,400 in 2007 and 3,900 women in 2009.
Women between ages 25 and 39 and women who already had one or more children were more likely to use long-acting contraception, the results showed. This supports the idea that most people consider long-acting contraception to be a method that should be used after child-bearing.
Long-acting contraception also has higher up-front costs than other methods, which may deter younger women

However, although women younger than 25 were less likely to use long-acting methods

Despite the rise in use of long-acting methods, the most common form of birth control used by women over age 35 was sterilization, and among women under age 35, other methods such as the pill remained more common.
