Other notable findings: Multiple births were relatively unchanged in recent years. Twins accounted for 33.2 per 1,000 total births in 2011.
Births of triplets and more also remained unchanged at 137 per 100,000.
Dr. Mitchell Maiman, chairman of obstetrics and gynecology at Staten Island University Hospital in New York City, said he expects that women will continue to postpone childbirth.
"More and more women are not only in the workforce, but more women are the primary breadwinner in the family," he said.
"So you are going to have more women who are delaying childbearing to enhance their careers. And you have amazing technology to enable them to accomplish that," Maiman said. "You are going to see older and older mothers."
