Realtor.com Data County Map — Listings Rolled Up by County
The market by county
Listings rolled up to their county FIPS code — a census-joinable key that 98.9% of rows carry. Circle area is listing volume; colour is whichever measure you pick.

Where this dataset holds the most listings
This map is built from aggregated fields only — coordinates are county averages, and the endpoint behind it never returns an address, listing URL, or property identifier. Those columns exist only on the Dataset page, where handing over real rows is the point.
