How these comparisons are calculated

Calculated from the Sep 2026 monthly rating update, using the same population as Chess67’s USCF statistics: US members classified as active in the published monthly records, excluding lifetime-coded records. Includes provisional ratings. These are Chess67 calculations, not official US Chess rankings. “Lower” is strictly lower; ties share a rank. National and state groups overlap.
