How This FIPS Code Works

38 063
38 = State FIPS (North Dakota)
063 = County FIPS

Census ACS API — Python 38063
import requests

url = "https://api.census.gov/data/2022/acs/acs5"
params = {
    "get":  "NAME,B19013_001E,B01003_001E",
    "for":  "county:063",
    "in":   "state:38",

SQL — filtering by county FIPS 38063
-- 5-digit combined FIPS (state + county)
SELECT * FROM your_table WHERE county_fips = '38063';

-- Some datasets store state and county separately
SELECT * FROM your_table
WHERE state_fips = '38'
  AND county_fips = '063';

-- ⚠ Never cast to integer — leading zeros are lost:
-- county_fips = 38063 is WRONG for this county

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

  county    = "063",
  year      = 2022
)
Zero-padding reminder: FIPS codes must always be stored and compared as zero-padded strings. 38 (not 38) and 063 (not 63) — losing the leading zeros is one of the most common data-join bugs in federal datasets. Full guide →

ZIP Codes in Nelson County

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