Startups per Capita — By County
Operating companies per 100,000 residents. Counts by category (primary_type_id = 1); excludes only acquired/merged/defunct companies, not unset status -- most companies in the graph have never had a status backfilled, so treating unset as inactive undercounted real companies (operator decision 2026-07-29). Matches oluwadi's own Operating Companies count exactly.
