Get data: gcd_rows() returns typed tibbles with place names beside codes, every category the filters don’t exclude, the API’s advisories as messages, and a gcd_meta attribute; large results download in full as CSV. gcd_values() lists the category combinations a filter covers.
Lookup tables: gcd_dimension() returns districts, schools, counties, tracts, block groups and demographic groups.
Places by name: district, school and county arguments match names exactly (ignoring case, accents and a trailing “County”, and including former names) and stop with candidates when a name is ambiguous.
gcd_locate() finds the county, tract, block group, school district and zoned schools for points, or for addresses geocoded locally with the U.S. Census batch geocoder (addresses never reach the Georgia Civic Data API).
