Census ACS API — Python 16013
import requests

SQL — filtering by county FIPS 16013
-- 5-digit combined FIPS (state + county)
SELECT * FROM your_table WHERE county_fips = '16013';

-- Some datasets store state and county separately
SELECT * FROM your_table
WHERE state_fips = '16'
  AND county_fips = '013';

-- ⚠ Never cast to integer — leading zeros are lost:
-- county_fips = 16013 is WRONG for this county

)
Zero-padding reminder: FIPS codes must always be stored and compared as zero-padded strings. 16 (not 16) and 013 (not 13) — losing the leading zeros is one of the most common data-join bugs in federal datasets. Full guide →
