A decline in the adolescent birth rate in 2004 to its lowest recorded level is one among many findings in the federal government's annual monitoring report on the well-being of the nation's children and youth. The report covers the most recent years for which data are available and, in the case of adolescent births, reveals a prevalence of 22.1 births for every 1,000 females between the ages of 15 and 17 years in 2004, down from 22.4 for every 1,000 in 2003. Other noteworthy findings from "America's Children in Brief: Key National Indicators of Well-Being, 2006," reflect changes in the infant mortality rate, prevalence of overweight, and rising math and reading scores among elementary school students.
