While the percentage of babies born prematurely has risen by one-third since the 1980s, the rate dropped by 1 percent in 2007 compared to the previous year to a rate of 12.7 percent. Premature or preterm babies are defined as those born before the 37th week of pregnancy. Babies born between the 37th and 40th week are considered full-term. This data comes from a recent national vital statistics report from the National Center for Health Statistics, a part of the CDC, called Births: Preliminary data for 2007. The report contains data on all births in the U.S. during 2007, including information on the rates of premature in each state. Several states still have relatively high rate of premature births and the top 10 are listed below, with the percentage of all live births that were premature appearing in parentheses.

The top 10 states with the highest rates of preterm births are:

Mississippi (18.3%)
Alabama (16.6%)
Louisiana (16.5%)
South Carolina (15.5%)
Kentucky (15.2%)
Delaware (14.3%)
Nevada (14.3%)
Tennessee (14.2%)
Arkansas (13.9%)
West Virginia (13.9%)
