The ideal that all Americans have equality of opportunity regardless of their economic status at birth is the crux of the American Dream and a defining element of our national psyche. This study investigates the health and status of that dream by analyzing economic mobility—Americans’ movement up and down the economic ladder—during the past generation. Pursuing the American Dream: Economic Mobility Across Generations is an update to the Economic Mobility Project’s (EMP) foundational work, Getting Ahead or Losing Ground: Economic Mobility in America, originally released in 2008 (author introduction).
