Relationship file (crosswalk) for ZCTAs by state — zcta_state

Each of these tables contains ZIP Code Tabulation Areas (ZCTAs), their intersecting counties and the states (state name, abbreviation, state FIPS code) they are nested in. It's used in get_census_data() for retrieving ZCTA-level census data by state, as tidycensus::get_acs() (CRAN version) currently does not support obtaining state-specific ZCTA-level data.
