Older Moms Factor into Possible New Baby Boom

The USA could be facing a baby "boomlet", according to federal data that shows a record number of babies were born in 2007.

The National Center for Health Statistics reported the 4,315,000 births in 2007 as "provisional" data.

One expert attributed three factors to the potential baby boom:

1. More immigrants having children

2. Professional women delaying childbearing until their 40s

3. More women in their 20s and 30s in the population, keeping the fertility rate high.
