The entertainingly-named Moving Momentarily calls our attention to WMATA’s recently released ridership demographics. The short version: Metrorail riders are typically college-educated, high-earning commuters, while Metrobus riders are less likely to have a college degree, and earn about 2/3 of what Metrorail riders earn. So, you know, when Metrobus service gets cut, it actually DOES disproportionately affect people who are dependent on public trainsit.
But Moving Momentarily does find an unexpected benefit (and possible WMATA revenue source!) from these numbers: look at all those educated top earners on the train! Metro speed dating, anyone?
