How This FIPS Code Works

35 003
35 = State FIPS (New Mexico)
003 = County FIPS

The 5-digit FIPS code 35003 is formed by combining the 2-digit state identifier 35 (New Mexico) with the 3-digit county identifier 003. Together they uniquely identify Catron County in every US federal dataset. No two counties share the same 5-digit FIPS code.

Census ACS API — Python 35003
import requests

url = "https://api.census.gov/data/2022/acs/acs5"
params = {
    "get":  "NAME,B19013_001E,B01003_001E",
    "for":  "county:003",
    "in":   "state:35",

SQL — filtering by county FIPS 35003
-- 5-digit combined FIPS (state + county)
SELECT * FROM your_table WHERE county_fips = '35003';

-- Some datasets store state and county separately
SELECT * FROM your_table
WHERE state_fips = '35'
  AND county_fips = '003';

-- ⚠ Never cast to integer — leading zeros are lost:
-- county_fips = 35003 is WRONG for this county

get_acs(
  geography = "county",
  variables = c(income = "B19013_001E", pop = "B01003_001E"),

  county    = "003",
  year      = 2022
)
Zero-padding reminder: FIPS codes must always be stored and compared as zero-padded strings. 35 (not 35) and 003 (not 3) — losing the leading zeros is one of the most common data-join bugs in federal datasets. Full guide →

ZIP Codes in Catron County

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