2011 resulted in a record low birth rate for the United States. At a rate of 12.7 per 1,000 people, the birth rate is at the lowest ever reported for the nation.
In a report published in the March 2013 issue of Pediatrics by Brady Hamilton PhD, of the CDC in Atlanta, and colleagues at the agency and the Johns Hopkins Bloomberg School of Public Health in Baltimore, 3,953,593 babies were born in the U.S., which is 1 percent fewer than in 2010 and 4 percent fewer than in 2009.
General fertility rates fell by 1 percent as well hit a record low of 63.2 percent. This rate is defined as the number of birth per 1,000 women ages 15 through 44.
The birth rate among teens (15-19) fell by 8 percent which established the rate at a historic low of 31.3 birth per 1,000 women. This is down 49 percent from 1991, which was the most recent peak in teen birth rates.
Rates fell for 20 to 29-year-old's and rose for women ages 35 through 44.
