What’s behind Castro Valley’s civic life grade
Castro Valley isn’t graded on civic life: it’s unincorporated, so its nonprofits can’t be counted reliably (mailing addresses don’t follow its boundary), its library is a branch of Alameda County Library, so there is no town figure for visits and the volunteering estimate doesn’t cover enough of it.
Civic life counts registered nonprofits, library visits and online volunteering groups, so it can miss civic life that runs through congregations, mutual aid or neighbors looking out for each other.
