How good the register is

The statement is the only official list of associations, and it is only as current as the last filing.

66 of 508 last filed it more than two years before the register was copied. They are counted here but have no page of their own.
The county is free text. Associations wrote “Sonoma” 9 different ways; each one is read back to the county.
236 of 508 have had their corporate powers suspended at some point, and 9 corporations here are suspended today. A suspension is the corporation’s, not the community’s — § 5405(d).
