How This FIPS Code Works

01 105
01 = State FIPS (Alabama)
105 = County FIPS

The 5-digit FIPS code 01105 is formed by combining the 2-digit state identifier 01 (Alabama) with the 3-digit county identifier 105. Together they uniquely identify Perry County in every US federal dataset. No two counties share the same 5-digit FIPS code.

Census ACS API — Python 01105
import requests

url = "https://api.census.gov/data/2022/acs/acs5"
params = {
    "get":  "NAME,B19013_001E,B01003_001E",
    "for":  "county:105",
    "in":   "state:01",

SQL — filtering by county FIPS 01105
-- 5-digit combined FIPS (state + county)
SELECT * FROM your_table WHERE county_fips = '01105';

-- Some datasets store state and county separately
SELECT * FROM your_table
WHERE state_fips = '01'
  AND county_fips = '105';

-- ⚠ Never cast to integer — leading zeros are lost:
-- county_fips = 1105 is WRONG for this county

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

  year      = 2022
)
Zero-padding reminder: FIPS codes must always be stored and compared as zero-padded strings. 01 (not 1) and 105 (not 105) — losing the leading zeros is one of the most common data-join bugs in federal datasets. Full guide →

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