Yeah, it's rather odd. BART's equivalent data (though not as nicely plotted) is here: https://www.bart.gov/sites/default/files/docs/StationProfile2015_HomeOrigi

Pulling up some random stations shows that the median income at most BART stations is $50k-$75k, which is right what I would expect. Even at the downtown/FiDi ones like Embarcadero and Montgomery, it's just a bit above $75k. Median income in SF is about $95k, so BART ridership skews less wealthy than the area as a whole.
