How This FIPS Code Works

12 091
12 = State FIPS (Florida)
091 = County FIPS

Census ACS API — Python 12091
import requests

url = "https://api.census.gov/data/2022/acs/acs5"
params = {
    "get":  "NAME,B19013_001E,B01003_001E",

SQL — filtering by county FIPS 12091
-- 5-digit combined FIPS (state + county)
SELECT * FROM your_table WHERE county_fips = '12091';

-- Some datasets store state and county separately
SELECT * FROM your_table
WHERE state_fips = '12'
  AND county_fips = '091';

-- ⚠ Never cast to integer — leading zeros are lost:
-- county_fips = 12091 is WRONG for this county

  geography = "county",
  variables = c(income = "B19013_001E", pop = "B01003_001E"),

)
Zero-padding reminder: FIPS codes must always be stored and compared as zero-padded strings. 12 (not 12) and 091 (not 91) — losing the leading zeros is one of the most common data-join bugs in federal datasets. Full guide →
