It is unclear which definition of "San Francisco" they are using. Is it just the city of San Francisco, the San Francisco-Oakland-Hayward, CA Metropolitan Statistical Area, or the San Jose–San Francisco–Oakland, CA Combined Statistical Area? I would guess that since San Jose is not listed separately, they are using the CSA, which includes a lot of outlying areas.
