Coverage
The registry lists 11,858 facilities in Pennsylvania against a BLS QCEW benchmark of 14,583 manufacturing establishments (2024) — coverage of 81.3%. The benchmark is a floor: QCEW counts establishments covered by unemployment insurance and so excludes most sole proprietors and some contract operations. The real number of manufacturing sites is therefore higher than the benchmark, and this percentage overstates coverage rather than understating it. Where it exceeds 100%, the registry lists more sites than QCEW counts establishments — which is expected in states with many small or single-person operations, and is also where duplicate listings would show up first.
