I thought you had to realize that comparing DC to a state like California wasn't going to be an apples-to-apples comparison, which is why I wrote, "and you know it." I'm sorry for making assumptions.
You're also right, I was sloppy with my citation. I looked into the source data, and I believe Wikipedia's second table may be wrong here. Here is B19301 from the 2010 census. The Bridgeport MSA is first: https://data.census.gov/table/ACSDT5YSPT2010.B19301?q=b19301...
Unfortunately, the table on Wikipedia is uncited (beyond the 2010 census) and was added by an anonymous IP address editor, so I don't know how they got their numbers. I'll double check my work and update the article if I don't find anything else.
Generally, though, my point is that if you compare the states and DC, you'll find that DC is an outlier on a lot of dimensions. If you compare the DC metro area with other MSAs, a lot of that exceptionalism goes away.
