The Concord, and Dublin/Pleasanton/Livermore UAs are suburbs that only exist because of SF/Oakland, are connected by metro lines to them, and are only separated from the SF UA by parkland. The San Jose UA isn't physically separated at all. But arbitrary rules about population density somehow makes these all separate urban areas/metros/cities? Together they have about 6 million people. There are more urban areas within the Bay Area, making up 1.5-2 million more people, but they're a bit more separated, and have worse public transit connections...for some of them, it feels like it could be accurate to exclude them from a combined SF/SJ urban area (Santa Rosa, Petaluma, Napa, Fairfield, Gilroy, Vacaville?) but others feel like maybe they should be included (Vallejo, Antioch).
Imagine if Newark and NYC were considered separate urban areas/metro areas, because Jersey City was mostly warehouses and office parks instead of being densely populated, and because the suburbs stretching north along the Hudson were mostly parkland, and because Newark was bigger and attracted more commuters. The two places still have residents who identify as being in the same region/metro area, they're heavily connected by public transit, share media markets, share sports teams, and a bunch of cultural stuff, and send lots of commuters to each other, as well as to/from their shared suburbs, but the census says they're totally separate. The relationship between the SF and SJ MSAs/UAs feels kinda like that lol.
