Coverage
The registry lists 15,071 facilities in Illinois against a BLS QCEW benchmark of 19,324 manufacturing establishments (2024) — coverage of 78.0%. 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.
