A typical household in Scarsdale, New York earns nearly a quarter of a million dollars a year, or more than 13 times the income of a typical household in Macon, Mississippi of $18,232. Some states have much more economic diversity. Many of the wealthiest states are also home to the poorest places not just in the state, but also in the country. Median incomes in Cumberland, Maryland and Camden, New Jersey are more than $40,000 lower than the typical household annual income across the state.

In New York there are 35 towns where the median household income is more than double the national median income of $53,482. All 35 of those New York towns are within 75 miles of Manhattan. By contrast, the median household income in Maine’s richest town is less than the national median income. Maine’s largest city has a population of less than 67,000 residents — a fraction of the 1.6 million residents in New York City’s Manhattan borough alone.
