How This FIPS Code Works

42 103
42 = State FIPS (Pennsylvania)
103 = County FIPS

SQL — filtering by county FIPS 42103
-- 5-digit combined FIPS (state + county)
SELECT * FROM your_table WHERE county_fips = '42103';

-- Some datasets store state and county separately
SELECT * FROM your_table
WHERE state_fips = '42'
  AND county_fips = '103';

-- ⚠ Never cast to integer — leading zeros are lost:
-- county_fips = 42103 is WRONG for this county

Zero-padding reminder: FIPS codes must always be stored and compared as zero-padded strings. 42 (not 42) and 103 (not 103) — losing the leading zeros is one of the most common data-join bugs in federal datasets. Full guide →
