The Changing Shape of American Cities

February 2015 — The last two decades have brought dramatic changes to many American cities. Most cities in the United States in 1990 had a “donut” shape, with wealthier residents in a booming suburban ring surrounding a decaying core. Today cities are increasingly resembling what has been called a new donut – with three, rather than two rings. The center has grown much more desirable to educated, higher-income residents, especially young adults under the age of 35. Poverty, meanwhile, is migrating outwards, creating an “inner ring” of urban and early suburban neighborhoods around the core, where per capita incomes have fallen and education rates are stagnant. Beyond the inner ring, an outer ring of newer and larger suburbs continues to add population.

The line that divides DC
No it’s not a party line. It’s an almost perfectly straight line running north-south along 16th Street, passing through the White House, and then continuing along the Potomac River to the south. It divides two very different sides of the DC area.
