About Our Data
All demographic metrics, ZIP codes, and geographic boundaries published on zips.us.com are regularly aggregated from official government statistics, including the U.S. Census Bureau, United States Postal Service (USPS), National Weather Service, American Community Survey, and the IRS.
Frequently Asked Questions
Demographic stats—like population counts, median household income, and age breakdowns—update once a year when the U.S. Census Bureau releases its annual American Community Survey (ACS) estimates.
Discrepancies usually come down to data sources, survey years, and geographic definitions. Some sites use decennial Census data releases (like 2010 or 2020), while others use the latest 5-year American Community Survey (ACS) estimates or proprietary commercial projections.
Instead of looking for an absolute 'exact' number, treat differing stats as a range or trend line. Higher-level estimates still offer strong comparative value. For example, if three separate sources show a ZIP code's median income well above the state average, the overall economic profile remains reliable regardless of minor variations in the exact dollar amount.

A city's overall statistics average data across all its neighborhoods, whereas individual ZIP codes highlight more localized statistics. Income, median home values, age distributions, etc. can vary wildly from one ZIP code to another within the same city borders.
The USPS assigns a default 'preferred city name' to each ZIP code based on the location of the primary post office serving that route. Even if someone resides in an adjacent municipality or unincorporated area, the postal system routes mail using that primary post office city name.
The extra four digits pinpoint a specific delivery location within a 5-digit ZIP code. They usually mark a specific city block, an apartment building, a group of offices, or an individual high-volume mail receiver.
