The source behind the name

USGS GNIS Populated Place names in all 50 states and DC. Features in the historical extract or explicitly named historical are excluded; duplicate decision records with identical identities and coordinates are collapsed. GNIS points identify names, not legal or neighborhood boundaries, current occupancy, school attendance or a statistical population. Nearby Census places and tracts remain separately named geographies. Name completeness and currency vary; this is not a claim to include every locally used neighborhood name.
