How This FIPS Code Works

24 035

SQL — filtering by county FIPS 24035
-- 5-digit combined FIPS (state + county)
SELECT * FROM your_table WHERE county_fips = '24035';

-- Some datasets store state and county separately
SELECT * FROM your_table
WHERE state_fips = '24'
  AND county_fips = '035';

-- ⚠ Never cast to integer — leading zeros are lost:
-- county_fips = 24035 is WRONG for this county

Zero-padding reminder: FIPS codes must always be stored and compared as zero-padded strings. 24 (not 24) and 035 (not 35) — losing the leading zeros is one of the most common data-join bugs in federal datasets. Full guide →
