We already knew that, beginning roughly with the start of the
financial crisis, the metro D.C. area was gaining in prominence
relative to other big American cities. D.C. suburbs
now make up six of the 10 richest counties in America,
including the top three.
New Census data shows that the D.C. area has grown faster than
anywhere else in the past decade. Three D.C. suburbs, led by
Arlington County,
were among the four municipalities showing the greatest income
gains over the period measured between Censuses, 2000-2009. The
median household income in Arlington County increased $12,705 in
that timespan.
