The number of births in the United States has been steadily increasing since 1997. In 2006 there were 4,265,996 babies born in the United States, 10% more than in 1997 -- just short of the record high of 4.3 million babies in 1957 at the peak of the Baby Boom years. Interim data through June 2007 shows a continuing increase. The 1957 record may have been broken in 2007.
