What's going on with Alcatraz Island? It's shaded "primarily service class"! Are there NPS personnel living there full time?

Alcatraz is lumped into the same census tract as the Presidio.

And why is Santa Clara County left out?

Not only that: Alameda county is not a part of SF metro. Especially Fremont, which is part of Fremont-Milpitas-Union City tri-city metro.
