The US Census Bureau released its American Community Survey data, and once again a striking detail comes into focus. The five counties with the highest median income in all of America are all near Washington DC.
Although it has come to be expected, this is still an astounding realization. Some of our major cities are built around lucrative industries. New York City is built around Wall Street and the financial sector, a multi-billion dollar industry. Hollywood is built around movies and entertainment, a multi-billion dollar industry. Silicon Valley is built around the technology boom, an unprecedented event that is creating billionaires left and right.
Washington DC is built around the Federal Government, a trillion dollar industry.
It seems like this is discussed each time the new survey inevitably puts several counties surrounding DC at the top of the list. But I think many people are drawing the slightly wrong conclusion from this data.
