The birthrate among U.S. teenagers dropped 8 percent last year to another record low, the latest sign of major progress in efforts to reduce teen pregnancies, a federal health agency reported on Thursday.
The rate last year fell to 22.3 births per 1,000 teenage girls aged 15 to 19, down from 24.2 births in 2014, the U.S. Centers for Disease Control and Prevention said in a preliminary study based on birth certificate data.
