How good the register is

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

85 of 1,067 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 “Contra Costa” 20 different ways; each one is read back to the county.
450 of 1,067 have had their corporate powers suspended at some point, and 15 corporations here are suspended today. A suspension is the corporation’s, not the community’s — § 5405(d).
