According to a recent report by the Centers for Disease Control and Prevention (CDC), there were approximately 3,958,000 live births in the United States in 2012. These initial 2012 numbers from the CDC are "provisional," and subject to change.
The number of U.S. births in 2012 are quite similar to the 2011 totals. The current CDC total (subject to revision as well) of U.S. births for 2011 is 3,953,593.
In both 2011 and 2012, total annual births in the United States declined by approximately 9% relative to the pre-recession year of 2007, a year in which 4,316,233 babies were born.
In 2007, the U.S. fertility rate was 69.3 births per 1000 women ages 15-44. According to the CDC, the U.S. fertility rate was 63.2 in both 2011 and 2012.
While both the birth rate and total births provisional numbers for 2012 are well below the final numbers for 2007, these initial 2012 numbers suggest that the so-called Baby Bust has slowed dramatically and leveled off.
