Sources and methodology

ShowWhere the seat counts and district lines come from.

Seat counts by party come from each chamber's official member list or the legislature's own published count, reviewed November 2, 2026, before the November 3 election. Each state and chamber page names its source.

District lines come from the U.S. Census Bureau's state legislative district boundary files. D.C. has a council rather than a state legislature, so it is not listed.
