The document provides a historical report on opportunity in the United States from 1970 to 2010. It finds that overall conditions for opportunity improved over the four decades measured, but the path was uneven. The decade from 1990 to 2000 saw the greatest progress, while the 1970s and 2000s saw declines in some measures of opportunity. At the state level, nearly every state saw gains in overall opportunity, led by Virginia. Only Nevada and Michigan saw declines. The report examines trends in indicators related to jobs/economy, education, and community over the four decades.
