How This FIPS Code Works

56 009
56 = State FIPS (Wyoming)
009 = County FIPS

Census ACS API — Python 56009
import requests

url = "https://api.census.gov/data/2022/acs/acs5"

SQL — filtering by county FIPS 56009
-- 5-digit combined FIPS (state + county)
SELECT * FROM your_table WHERE county_fips = '56009';

-- Some datasets store state and county separately
SELECT * FROM your_table
WHERE state_fips = '56'
  AND county_fips = '009';

-- ⚠ Never cast to integer — leading zeros are lost:
-- county_fips = 56009 is WRONG for this county

Zero-padding reminder: FIPS codes must always be stored and compared as zero-padded strings. 56 (not 56) and 009 (not 9) — losing the leading zeros is one of the most common data-join bugs in federal datasets. Full guide →
