The United States continues to have one of the highest rates of adolescent childbearing and pregnancy rates in the developed world, despite a substantial 17% decline in its teenage pregnancy rate in the 1990s, according to a new cross-country study by The Alan Guttmacher Institute (AGI). Currently, U.S. rates are akin to those in the Russian Federation and several eastern European countries, including Bulgaria, and at least four times the rates in France, Germany and Japan.
