New data shows that teen birth rates fell at least 15% for all but two states (North Dakota and West Virginia) during 2007-2011, with rates falling 30% or more in seven states: Arizona, Colorado, Florida, Idaho, Minnesota, Nevada, and Utah.

• Declines were steepest for Hispanic teens (34%), followed by declines of 24% for non-Hispanic black teens and 20% for non-Hispanic white teens.

• Public health emphasis has been placed on teen pregnancy prevention, because infants born to adolescents are at elevated

risk of low birth weight, preterm birth, and dying in infancy, compared with infants born to women ages 20 and over.
