Tennessee is following the national trend of fewer adolescent pregnancies. New federal statistics show that nearly every state in the union saw a decline in teen births from 2007 to 2010. The biggest drop occured in Arizona at 29 percent, while Mississippi had the highest rate. There were 55 teen births in Mississippi per 1,000 girls, though the rate there is also declining. Pregnancies among Tennessee girls between the ages of 10 and 17 fell 25% between 2007 and 2010. There were just over 2600 pregnancies recorded in that age bracket in 2010.
