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.
