The majority of girls in the United States do not have sex before the age of 19, a change from earlier years, a new report shows.

Between 2006 and 2010, about 57 percent of girls ages 15 to 19 said they had never had sex, an increase from 49 percent in 1995, according to the report from the Center for Disease Control and Prevention (CDC).

In addition, those who are having sex are increasingly using highly effective methods of contraception. The report said that 60 percent of sexually active girls ages 15 to 19 said they used contraception methods such as an intrauterine device, the pill, a patch, ring or injectable contraception — an increase from 47 percent who said the same in 1995.

The portion of teens who said they had not had sex was about the same across all ethnic groups.

Younger teens were less likely to have had sex: 73 percent of girls ages 15 to 17 reported never having had sex, compared with 36 percent of girls ages 18 and 19, the report said.
