The American dream is defined in the map below as having uphill economic mobility (The opportunity to become richer than you were born into).
Economic mobility is greater among wealthier economies than among developing economies.
Whereas the gap in absolute economic mobility between high-income and growing economies has been closing, absolute economic mobility in developing economies has stopped rising since the 1960s.
Africa and South Asia, the continents with most of the world’s poorest people, have the average lowest economic mobility.
