Using FIPS Code 16057 in Code

Common patterns for querying federal datasets by this county's FIPS code. The leading zeros are significant — always treat FIPS codes as strings, not integers.

import requests

url = "https://api.census.gov/data/2022/acs/acs5"
params = {
    "get":  "NAME,B19013_001E,B01003_001E",
    "for":  "county:057",
    "in":   "state:16",
    "key":  "YOUR_CENSUS_API_KEY",
}
r = requests.get(url, params=params)
data = r.json()  # [[header...], [Latah County, Idaho, income, pop, ...]

-- 5-digit combined FIPS (state + county)
SELECT * FROM your_table WHERE county_fips = '16057';

-- Some datasets store state and county separately
SELECT * FROM your_table
WHERE state_fips = '16'
  AND county_fips = '057';

-- ⚠ Never cast to integer — leading zeros are lost:
-- county_fips = 16057 is WRONG for this county
