Data Sources, Vintages & Limitations
- Population, income & home value: U.S. Census Bureau, American Community Survey (ACS) 5-Year Estimates, 2018–2022 (2022 vintage). Tables: B01003 (Total Population); B19013 (Median Household Income); B25077 (Median Home Value, owner-occupied). Geography: ZIP Code Tabulation Areas (ZCTAs) — ZCTA boundaries approximate postal ZIP boundaries and may not match exactly.
- Area classification ("Urban"): derived from USDA ERS Rural-Urban Commuting Area (RUCA) codes, 2010 revision (based on 2010 Census and ACS commuting data). RUCA is a commuting-pattern classification only. It does not measure — and should not be read as describing — schools, jobs, industries, traffic, amenities, safety, or lifestyle. It can be counterintuitive for small, island, or special-use ZCTAs.
- Home value trend: Zillow Home Value Index (ZHVI), smoothed, seasonally adjusted — all homes. ZHVI is a market price index and is reported separately from the ACS survey-based median home value above; the two measure different things and are never blended on this site. Latest ZHVI reporting month shown in the trend module. © Zillow. Data provided via Zillow Research; subject to Zillow's terms of use.
- Freshness: ACS data is released annually by the Census Bureau; this profile reflects the vintage above. Record last updated in our database: November 27, 2025.
- What we do not publish: we do not have verified ZIP-level data for schools, crime/safety, commute quality, climate, or amenities, so this profile makes no claims about them. See our methodology.
