The richest ZIP codes in Greater Washington include some of the same places every year — so how much do they really change?
Quite a bit, actually.
We took a look at the current 10 wealthiest ZIPs in the region and compared what they look like now — in terms of income, population, age and racial demographics — with what they were like in 2010, using Census data. (Spoiler alert: All of these places have gotten richer, and some considerably more than others.)
