Medicaid Dental Atlas
An interactive map that turns roughly 60 GB of federal dental claims into a compact, explorable view of access and utilization.
Compressing public data into something usable
The Medicaid Dental Atlas makes a large public dataset approachable at state, county, and ZIP3 granularity. It covers claims from 2018 through 2024 without asking the browser to carry the weight of the original source data.
The data pipeline reduces tens of gigabytes of raw federal claims into a compact static artifact that can be served cheaply and explored interactively. MapLibre GL handles the map, while DuckDB supports analytical work during preparation.
The result is a small, fast data product designed to help patterns emerge through direct exploration rather than a fixed set of charts.
