How This FIPS Code Works

53 067
53 = State FIPS (Washington)
067 = County FIPS

SQL — filtering by county FIPS 53067
-- 5-digit combined FIPS (state + county)
SELECT * FROM your_table WHERE county_fips = '53067';

-- Some datasets store state and county separately
SELECT * FROM your_table
WHERE state_fips = '53'
  AND county_fips = '067';

-- ⚠ Never cast to integer — leading zeros are lost:
-- county_fips = 53067 is WRONG for this county

Zero-padding reminder: FIPS codes must always be stored and compared as zero-padded strings. 53 (not 53) and 067 (not 67) — losing the leading zeros is one of the most common data-join bugs in federal datasets. Full guide →

ZIP Codes in Thurston County

ZIP codes do not align perfectly with county boundaries — a single ZIP code can span multiple counties, and a county can contain parts of many ZIP codes. The ratios below (from the Census 2020 ZCTA relationship file) show the land area share of each ZCTA that falls within Thurston County. Why FIPS ≠ ZIP →
