How This FIPS Code Works

01 121
01 = State FIPS (Alabama)
121 = County FIPS

The 5-digit FIPS code 01121 is formed by combining the 2-digit state identifier 01 (Alabama) with the 3-digit county identifier 121. Together they uniquely identify Talladega County in every US federal dataset. No two counties share the same 5-digit FIPS code.

Using FIPS Code 01121 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.

Census ACS API — Python 01121
import requests

url = "https://api.census.gov/data/2022/acs/acs5"
params = {
    "get":  "NAME,B19013_001E,B01003_001E",
    "for":  "county:121",
    "in":   "state:01",

r = requests.get(url, params=params)
data = r.json()  # [[header...], [Talladega County, Alabama, income, pop, ...]
SQL — filtering by county FIPS 01121
-- 5-digit combined FIPS (state + county)
SELECT * FROM your_table WHERE county_fips = '01121';

-- Some datasets store state and county separately
SELECT * FROM your_table
WHERE state_fips = '01'
  AND county_fips = '121';

-- ⚠ Never cast to integer — leading zeros are lost:
-- county_fips = 1121 is WRONG for this county

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

  county    = "121",
  year      = 2022
)
Zero-padding reminder: FIPS codes must always be stored and compared as zero-padded strings. 01 (not 1) and 121 (not 121) — losing the leading zeros is one of the most common data-join bugs in federal datasets. Full guide →

ZIP Codes in Talladega County
