The Washington Post analyzed census data to find Zip codes where people rank highest on a combination of income and education. They are Super Zips.
The ranks, ranging from 0 to 99, represent the average of each Zip’s percentile rankings for median household income and for the share of adults with college degrees. Super Zips rank 95 or higher. This
The map at top shows the nation’s 650 Super Zips. Among them, the typical household income is $120,272, and 68 percent of adults hold college degrees. That compares with $53,962 and 27 percent for the remaining 23,925 Zips shown. Only Zips with at least 500 adults are displayed.
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. (Wash Post)
