• get_geography

  Full record for one geography: attributes, parent chain up to the country, child counts by level, and the source it came from (licence, vintage, last fetched).

• related_geographies

  Links between geographies that overlap without nesting, with population shares. Districts: for a precinct, county, town, city (place) or ZIP, the congressional, state senate and state house districts it falls in; for a district, the precincts, counties, towns, cities or ZIPs ins…
