Census ACS API — Python 49053
import requests

url = "https://api.census.gov/data/2022/acs/acs5"
params = {
    "get":  "NAME,B19013_001E,B01003_001E",

SQL — filtering by county FIPS 49053
-- 5-digit combined FIPS (state + county)
SELECT * FROM your_table WHERE county_fips = '49053';

-- Some datasets store state and county separately
SELECT * FROM your_table
WHERE state_fips = '49'
  AND county_fips = '053';

-- ⚠ Never cast to integer — leading zeros are lost:
-- county_fips = 49053 is WRONG for this county

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

)
Zero-padding reminder: FIPS codes must always be stored and compared as zero-padded strings. 49 (not 49) and 053 (not 53) — losing the leading zeros is one of the most common data-join bugs in federal datasets. Full guide →

ZIP Codes in Washington County

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