'CSA' and 'MSA' boundaries are based on county-level borders (counties are the next administrative unit below 'states' in the US). This leads to areas very far from central cities being included in the CSA numbers (San Bernardino county in California goes all the way to the Nevada border, for example).
I tried a while ago to figure out the 'real' numbers for the LA area, trimming off disconnected zones like Lancaster/Palmdale. It was a bit less than 16 million, as I recall. The DC-Baltimore blob is very diffuse and sprawls all over the place, all the way into West Virginia. It feels very different from a typical 10+ million-person megacity.
