Dec. 21, 2010 -- New data on U.S. births have broken three records, the CDC reported today.
Record No. 1: The U.S. teen birth rate is the lowest since record-keeping began in 1940.
Record No. 2: One in three U.S. babies (32.9%) are delivered by C-section.
Record No. 3: The U.S. birth rate is the lowest ever, at 13.54 births per 1,000 total population.
The data are from an analysis of nearly all U.S. birth certificates from 2009 by the CDC's Division of Vital Statistics.
The only group to see a birth rate increase was women in their early 40s.
Although unmarried women also had fewer births, the percentage of mothers who are unwed rose to 41%.
Here are some other interesting statistics from the CDC's preliminary 2009 vital statistics on U.S. births:
