Geography
map_precinct
A map precinct is a geographic precinct boundary sourced from a state or county election authority. Because precinct definitions vary across sources and are periodically redrawn, this table preserves both the Indigo-assigned identifier and the upstream source identifiers so that precincts can be joined back to results data and traced to their origin.
