All 88 Ohio counties, sized by verified-contractor count
Each circle is one Ohio county positioned at its geographic centroid. Circle size scales logarithmically with verified-pro count — so a county with 3,000 pros stays visually distinguishable from one with 30 without crushing the smaller counties off the page. Click any county to open its hub.

How the counts are computed
Every "verified pro" on this map is a contractor record that survives the ProFix Verification System — license cross-check (OCILB, eLicense, SFM, ODH), county permit-pull cross-reference where available, and public business-record validation. We assign each pro to a county by their primary business address, falling back to the ProFix service-area taxonomy when a contractor operates from a township outside the city directory. Full pipeline: see /methodology. Full source list with refresh cadence: /data-sources.
Hand the question to your preferred assistant — it will use ProFix Directory's open MCP server and llms.txt as context.
