April 10, 2012 -- The number of babies born to U.S. teens has reached a historic low.
New statistics from the CDC show the teen birth rate in 2010 dropped by 9% from 2009 to a new low of 34.3 births per 1,000 women aged 15-19.
That sets several records:
"If the 1991 rates had prevailed through the years 1992-2010, there would have been an estimated 3.4 million additional births to teenagers during that period," CDC researchers Brady Hamilton, PhD, and Stephanie Ventura write in their report.
Researchers say the public health impact of this decline is substantial because of the increased health risks faced by teen mothers and their infants. Public health costs associated with teen childbearing are estimated at $10.9 billion each year.
They credit the drop in teen birth rates to more teens using contraceptives when they have sex for the first time, and also teens using dual methods of birth control, such as condoms and birth control pills.
The drop in the teen birth rate from 2009-2010 included teens from all ages and ethnic groups. But there are still some gaps.
Teen birth rates dropped in all but three states: Montana, North Dakota, and West Virginia.
Overall, teen birth rates tended to be highest in the South and Southwest and lowest in the Northwest and upper Midwest.
Researchers say some of the variation in teen birth rates between states may reflect racial and ethnic differences.
For example, 2010 teen birth rates ranged from:
