Use the county data

Use the public county JSON as a small, reproducible input for a coding mission. A useful example is validating FIPS codes, grouping rows by state and producing a documented report that another person can run.

County references are sample public inputs; a page does not represent a completed customer mission or a supported government-system integration.
