USAviz makes public place data easier to understand. We turn raw, hard-to-use datasets into human-readable pages for ZIP codes, counties, metro areas, states, and area codes.
Each place page is organized into a consistent set of sections, such as:
We also publish versioned snapshot releases so the site can be served quickly and consistently.
We collect, normalize, validate, and visualize public data. Each release is timestamped and includes source/vintage notes so you can see what changed over time.
We also use Vercel Analytics to understand performance and improve the Service. Details are described in our Privacy Policy.
Learn more about our approach on Methodology and see dataset links on Sources.
Some geographies (especially ZIP-level estimates) can have higher margins of error than county or state data. Small differences should be interpreted as directional signals, not precise measurements.
USAviz is an independent project. If you have product feedback or suggestions, you can reach the founder at john@usaviz.com.
