**California Governor Gavin Newsom signed SB 1387 on September 30, 2026, after the Legislature gave final approval in late August with near-unanimous support in both chambers.** The measure adds “Jewish” as a distinct ethnicity category for voluntary demographic data collection by state agencies, alongside its existing classification as a religion. It passed without recorded opposition and was backed by a broad coalition of Jewish organizations seeking improved tracking of antisemitism, health outcomes, and community needs in official statistics. With enactment already complete well ahead of the December 31 deadline, trader consensus at 96.5% “Yes” reflects the bill’s completed legislative and executive path. Only an improbable last-minute repeal or court block before year-end could alter the outcome, scenarios with no visible momentum in current reporting. The law phases in gradually, with forms updated starting 2029 and aggregate reporting from 2030, but the core statutory recognition is now in place.
