HYATTSVILLE, Md. (CBS) – A new report from the CDC finds the percentage of teen girls who have used the morning after pill has increased by more than ten percent over the past decade.

The report says that the use of emergency contraception by female teenagers who have had sexual intercourse at least once has increased from 8 percent in 2002 to 22 percent in 2011 through 2013.

Additionally, the study found that from 2011 to 2013, 97 percent of teen girls who had sex had used a condom at least once.

Researchers say in 2013, the U.S. birth rate for teens aged 15-19 dropped 57 percent. It was at its peak in 1991, according the report.

The report says the teen birth rate in the U.S. is still higher than those in other developed countries.
