Last week, the Center for Disease Control's National Center for Health Statistics released a preliminary report on their 2005 data on childbirth in the United States. Some notable facts include:

The birth rate for teenagers aged 15-19 fell to 40.4 births per 1,000 teenage girls from a peak of 61.8 births per 1,000 in 1991.

The percentage of births to unmarried mothers rose from 35.8% of total births in 2004 to 36.8% of total births in 2005.

The cesarean delivery rate is now 30.2% of all births, a record high. The rate of cesarean delivery has increased 46% since 1996.
