Geographic crosswalk files

State FIPS

State FIPS folder includes crosswalk files for state name, state abbreviation, and state FIPS code in .dta and .csv format. R users can use the tidycensus package to get FIPS code at the state and county levels. Here is an example of how to extract state name and FIPS from the file

library(tidycensus)
data(fips_codes)
fips_codes <- fips_codes %>%
  transmute(STATEFIP = as.integer(state_code),
            state_name) %>%
  distinct()
