“It is not so much the size of the gap between the rich and poor that drives segregation,” they write, “as the ability of the super-wealthy to isolate and wall themselves off from the less well-to-do.”

The interesting pattern: By income, the wealthy (households making more than $200,000 a year) are more segregated than the poor (families living under the federal poverty line). By education, people with college degrees are more segregated than people with less than a high school diploma. By occupation, the group that Florida has coined the “creative class” is more segregated than the working class.

New York, San Francisco and Boston may attract diverse populations: people working in high tech and low-wage retail, workers with master’s degrees and GEDs, parents pulling in six figures and minimum wages. But in these cities, mounting evidence suggests those people aren’t living anywhere near each other. Which is to say that they may be experiencing the very same city in very different ways.
