Every indicator on the platform traces to one of these public, county-level sources. Open a card for provenance, release, methodology, limitations, and the full indicator list for that source.
The year in a source name is its file or release version. Data years on each card is the span of measurement years actually present in the data, which can differ because one release often bundles several years.
