Observed active-set turnover
Monthly entries, returns, and departures from the filtered active-member set
Observed from monthly USCF rating records since December 1, 2025. These set changes are not confirmed new registrations, membership expirations, or renewals: records can also enter or leave because of source coverage, geography, or eligibility filters. “First observed active” means no earlier active snapshot is retained for that member in California, and changes occurring between snapshots may not appear.
