Abstract. Objectives To determine the impact on teenage pregnancy of interventions that address the social disadvantage associated with early parenthood and to assess the appropriateness of such interventions for young people in the United Kingdom.
The National Story. U.S. teen pregnancy and birth rates have declined dramatically over the past two decades and are now at historic lows. There has been significant progress in all 50 states and among all racial/ethnic groups. Even so, U.S. rates of teen childbearing remain far higher than in other comparable countries.
