FIPS - Identify what type of Census geography each FIPS code seems to be (block, county, etc.)

Usage

fipstype(fips)

Arguments

fips: vector of one or more Census FIPS with or without leading zeroes, as strings or numeric

Value

vector of types: "block", "blockgroup", "tract", "city", "county", or "state"

Details

NOTE: Does NOT check if fips is a real fips. For that, use fips_valid()

Note a number of length 11 is an ambiguous case this is able to resolve as either a complete tract fips or a blockgroup fips with a missing leading zero.

Examples

 fips_counties_from_statename("Delaware")
#> [1] "10001" "10003" "10005"
 fipstype(9001)
#> [1] "county"
 fipstype("10001")
#> [1] "county"
 
test_tract_missing0 =   4013116500   # 10 digits tract missing 0
test_tract_good     = "04013116500"  # 11 digits full tract includes leading 0 !!!!!!!!!!
test_bg_missing0    =   40131165002  # 11 digits blockgroup missing leading 0 !!!!!!!!!!
test_bg_good        = "040131165002" # 12 digits full blockgroup

fipstype(test_tract_missing0)
#> [1] "tract"
fipstype(test_tract_good)
#> [1] "tract"
fipstype(test_bg_missing0)
#> [1] "blockgroup"
fipstype(test_bg_good)
#> [1] "blockgroup"

fips_valid(test_tract_missing0)
#> [1] TRUE
fips_valid(test_bg_missing0)
#> [1] TRUE
