About this data
Data as of . Source: FCC Universal Licensing System (ULS) weekly amateur license database; county from U.S. Census Bureau geocoding. Aggregates only, no individual licensee data is shown. Aggregate figures © Ham Recruiter, CC BY 4.0.
How we count
- New ham: an active licensee whose first license was granted in the period.
- Address updates: a change of FCC mailing address, often a move into the area.
- Counts use each licensee’s current FCC address. Someone licensed here who later moved is counted where they live now.
- Each license keeps only its most recent event of each type, so two upgrades in one year count once.
- PO-box-only addresses often can’t be matched to a county, so rural counties are slightly undercounted.
100% of California licensees could be matched to a county.
