These 47 counties hold the nation’s largest cities, from New York to Nashville, and they are densely packed – 99% of the population lives in urban places as defined by the Census. Diversity is the key word. Only 60% of the population is white, 28% are Hispanic, 17% are African American and 9% are Asian. The median household income is about $53,000 here, often with large pockets of poverty in as well as pockets of wealth. The Big Cities are the most populous county type in the ACP and also the most Democratic. In 2012, President Barack Obama captured 65% of the votes from these counties and won them by some 31 percentage points.
