There are a lot of wealthy and educated people living in SuperZips around Washington D.C.:

Clarksville sits in one of the nation’s “Super Zips” — a term coined by American Enterprise Institute scholar and author Charles Murray to describe the country’s most prosperous, highly educated demographic clusters. On average, they have a median household income of $120,000, and 7 in 10 adults have college degrees…

A Washington Post analysis of the latest census data shows that more than a third of Zip codes in the D.C. metro area rank in the top 5 percent nationally for income and education. But what makes the region truly unusual is that so many of the high-end Zip codes are contiguous. They form a vast land mass that bounds across 717 square miles. It stretches 60 miles from its northern tip in Woodstock, Md., to the southern end in Fairfax Station, and runs 30 miles wide from Haymarket in Prince William County to the heart of the District up to Rock Creek Parkway.

One in four households in the region are in a Super Zip, according to the Post analysis. Since the 2000 Census on which Murray based his analysis, Washington’s Super Zips have grown to encompass 100,000 more residents. Only the New York City area has more Super Zips, but they are a much smaller share of the total of that region’s Zip codes and are more scattered…

Yet many who live in these rapidly evolving communities do not think of themselves as rich or elite. The cost of living, particularly for housing, eats up a large chunk of the two incomes it typically takes to afford a comfortable home in a good school district.

Interesting look at social class today in America; those on the upper end tend to argue they worked hard to get there, deserve what they have, and they aren’t really rich (though comparisons to much of the U.S., let alone most of the world, suggests otherwise). As the article goes on to note, a number of people are concerned about what the lack of interaction with others might mean down the road.

This is a story that has developed in recent years. For example, a number of people have noted that a large number of the wealthiest counties in the United States are in the Washington region. While conservatives tend to tie this wealth to the growth of big government (and the businesses associated with it), how come scholars haven’t looked at this more closely? There have been some studies of a few areas in the Washington metropolitan area, such as Prince George’s County and its large suburban black population or the growth of the edge city of Tysons Corner or responses to growing immigrant populations in Prince William County, but little look at the region as a whole. Perhaps this is a lingering artifact of American urban sociology’s emphasis on some “traditional big cities” like Chicago, New York City, Boston, and Philadelphia and not paying as much attention to newer big cities like Washington D.C., Dallas, Houston, Phoenix, Las Vegas, and others. Do we need something like a “Georgetown School” or “Brookings Institution School” of urban sociology?
