Megacities Mean Mega Income Gap (IMAGE) University of Rochester Caption The graph above tracks the income gap in different sized cities, with “0” representing rural areas and “10” the nation’s largest metropolitan regions. As shown, in 1979 (the green line), wage inequality was roughly equal regardless of where workers resided. Not so today. Now, the larger the city, the wider the wage gap among its workers. These income extremes grew steeper with each successive decade.
