How This FIPS Code Works

02 130

Census ACS API — Python 02130
import requests

SQL — filtering by county FIPS 02130
-- 5-digit combined FIPS (state + county)
SELECT * FROM your_table WHERE county_fips = '02130';

-- Some datasets store state and county separately
SELECT * FROM your_table
WHERE state_fips = '02'
  AND county_fips = '130';

-- ⚠ Never cast to integer — leading zeros are lost:
-- county_fips = 2130 is WRONG for this county

Zero-padding reminder: FIPS codes must always be stored and compared as zero-padded strings. 02 (not 2) and 130 (not 130) — losing the leading zeros is one of the most common data-join bugs in federal datasets. Full guide →
