How This FIPS Code Works

46 101
46 = State FIPS (South Dakota)
101 = County FIPS

Census ACS API — Python 46101
import requests

SQL — filtering by county FIPS 46101
-- 5-digit combined FIPS (state + county)
SELECT * FROM your_table WHERE county_fips = '46101';

-- Some datasets store state and county separately
SELECT * FROM your_table
WHERE state_fips = '46'
  AND county_fips = '101';

-- ⚠ Never cast to integer — leading zeros are lost:
-- county_fips = 46101 is WRONG for this county

Zero-padding reminder: FIPS codes must always be stored and compared as zero-padded strings. 46 (not 46) and 101 (not 101) — losing the leading zeros is one of the most common data-join bugs in federal datasets. Full guide →
