Sources and methodology
ShowHideWhere the district lines and seat counts come from.
District lines come from the U.S. Census Bureau's upper chamber boundary file (Cartographic boundary files, state legislative districts), which maps the districts the state reported to the Census Bureau. Where a state has redrawn its districts since then, the state's own maps are the official ones. District names are the Census Bureau's.
Census Bureau district name: State Senate District 37 (GEOID 19037).
Seats before the November 3, 2026 election, current to November 2, 2026, counted from the official member list. Source: Iowa Senate (opens in a new tab).
