The CalRoster labels county entries elected and appointed officials and does not publish a selection method for each individual role. Election.org therefore does not infer elected or appointed status from the title alone. The Secretary of State notes that each local jurisdiction supplies its own roster data; this is a dated public record, not a live officeholder feed.

  • Only the location, function, population, enrollment, and contact fields actually published.
  • The separate 2026 CalRoster reports the public-official roles and holder text shown above.

Not established by these records

  • Whether each governing or administrative role is elected, appointed, or mixed.
