About 62% of U.S. women from ages 15 to 44 use some form of contraception, and predictably, the pill is still the most popular. About 16% of women used it in 2011-2013, finds the latest report from the Centers for Disease Control and Prevention’s (CDC) National Center for Health Statistics. But the second most popular contraceptive may come as a surprise to many: 15.5% of women—just a hair behind the pill—choose female sterilization.
