The Washington Post is all about maps this week. First it was the “Eleven American Nations,” and now we have been introduced to “super zips,” the wealthiest and most educated zip codes in the United States—many of which are crowded around the Washington, D.C. metropolitan area.

This article seems to be moderately concerned with the future of Washington, D.C.—that the super-zips surrounding the nation’s capitol have created a “buffer” zone, insulating their wealthy, highly-educated residents from socioeconomic classes lower down the totem pole.

“Zip codes are large swaths of territory, and people from many different walks of life live in them. But many Washington neighborhoods are becoming more economically homogenous as longtime homeowners move out and increasing housing prices prevent the less affluent from moving in. The eventual result, in many cases, is a Super Zip. And because the contiguous Super Zips are surrounded by areas that are almost as well-off, it’s possible to live in a Super Zip and rarely encounter others without college degrees or professional jobs.”

William H. Frey, a demographer with the Brookings Institute referred to Washington as a “megalopolis of eggheads”–

“Washington is an example of how the country is compartmentalizing itself into clusters of people with different backgrounds and world views.  It’s a magnet for people who grew up elsewhere and came here because they want to be in a place that has an atmosphere of intellectual curiosity. But it means we’re somewhat isolated. A lot of people here may study and advocate for what’s going on in the rest of the country, but they can’t feel what’s going on if it doesn’t touch them.”

I don’t pretend to defend the idea that parts of Washington, D.C. are disconnected with the outside world and I understand that the contents of this study and article could be the cherry on top of the “Washington disconnect” narrative.  However, a very broad generalization has been made about the people living and working around Washington, D.C.  I don’t think it’s fair to paint D.C. professionals with such a broad stroke–especially one that is based solely on zip code or number of graduate degrees.
