How This FIPS Code Works

45 013
45 = State FIPS (South Carolina)
013 = County FIPS

Census ACS API — Python 45013
import requests

SQL — filtering by county FIPS 45013
-- 5-digit combined FIPS (state + county)
SELECT * FROM your_table WHERE county_fips = '45013';

-- Some datasets store state and county separately
SELECT * FROM your_table
WHERE state_fips = '45'
  AND county_fips = '013';

-- ⚠ Never cast to integer — leading zeros are lost:
-- county_fips = 45013 is WRONG for this county

)
Zero-padding reminder: FIPS codes must always be stored and compared as zero-padded strings. 45 (not 45) and 013 (not 13) — losing the leading zeros is one of the most common data-join bugs in federal datasets. Full guide →

ZIP Codes in Beaufort County

The ratios below (from the Census 2020 ZCTA relationship file) show the land area share of each ZCTA that falls within Beaufort County. Why FIPS ≠ ZIP →
