Wealth in the United States tends to be clustered in and around major cities, while rural areas have lower incomes. Look at the median household income view and note Obama’s strength on the wealthy East and West coasts. Keeping with median household income, look at Romney’s map to see how higher-income suburban and exurban counties tilted toward him, creating a doughnut effect in metro areas such as Dallas and Columbus, Ohio. In addition, note how owner-occupied housing isn’t always the best way to measure wealth. Many Romney counties won have higher ownership numbers, but in those rural places homes are also relatively inexpensive.
