SQL — filtering by county FIPS 56029
-- 5-digit combined FIPS (state + county)
SELECT * FROM your_table WHERE county_fips = '56029';

-- Some datasets store state and county separately
SELECT * FROM your_table
WHERE state_fips = '56'
  AND county_fips = '029';

-- ⚠ Never cast to integer — leading zeros are lost:
-- county_fips = 56029 is WRONG for this county

Zero-padding reminder: FIPS codes must always be stored and compared as zero-padded strings. 56 (not 56) and 029 (not 29) — losing the leading zeros is one of the most common data-join bugs in federal datasets. Full guide →
