Teen births hit new low

Officials attributed some flux to the recovering economy, though other experts said the increased use of contraception among teens is having the desired effect.

"I think the main thing behind this is increased contraceptive use, and better contraceptive use," Dr. Krishna Upadhya, a researcher at the Johns Hopkins School of Medicine, told Reuters.

The falling teen birthrate has led to 3.6 million fewer births among women that age since the 1990s, researchers said.

The statistics were published in the journal Pediatrics.
