Methodology & provenance

How this list is measured

This list counts registered US companies in Pennsylvania whose NAICS classification falls under sector 54 (Professional, Scientific, and Technical Services) — a live prefix-and-state aggregation over the multi-country company index, refreshed on a rolling cache. It counts registered legal entities on record, not establishments or employees; nothing is estimated or extrapolated. Email, phone and website figures are presence counts (contactable on record), never contact values — values exist only behind the credit-gated reveal.
