HouseHunter pins the FCC's December 2025 Fixed Broadband Summary by Geography Type for county 100/20 availability shares. Download that public ZIP from the map's Data Download page, then read only a few rows locally. Its share describes reported serviceable locations, not actual subscriptions, performance, affordability, or all residents.
Install the packages, then run the notebook cell.
