How This FIPS Code Works

16 077
16 = State FIPS (Idaho)
077 = County FIPS

Census ACS API — Python 16077
import requests

url = "https://api.census.gov/data/2022/acs/acs5"
params = {

SQL — filtering by county FIPS 16077
-- 5-digit combined FIPS (state + county)
SELECT * FROM your_table WHERE county_fips = '16077';

-- Some datasets store state and county separately
SELECT * FROM your_table
WHERE state_fips = '16'
  AND county_fips = '077';

-- ⚠ Never cast to integer — leading zeros are lost:
-- county_fips = 16077 is WRONG for this county

)
Zero-padding reminder: FIPS codes must always be stored and compared as zero-padded strings. 16 (not 16) and 077 (not 77) — losing the leading zeros is one of the most common data-join bugs in federal datasets. Full guide →

ZIP Codes in Power 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 Power County. Why FIPS ≠ ZIP →
