The transition to adulthood in the United States has changed in recent decades as many of the traditional milestones that mark adulthood have changed. Among these changes are increased participation and attainment in education; extenuation of educational completion and subsequent delayed participation in the labor force; and delays in child rearing. Accordingly, "America's Youth: Transitions to Adulthood" examines numerous aspects of the lives of youth and young adults, ages 14 to 24, in the United States over the last several decades. The report features status and trend data from multiple surveys on the distribution of youth and their family structure; on school-, employment-, and health-related factors; and on future plans.
