BLS QCEW, 2026Q1The figures above are County Business Patterns, which carries the size distribution but runs about two years behind. The Bureau of Labor Statistics publishes quarterly, so this is the same industry roughly 3 years later. The two count different universes, Census counts establishments with paid employees in the March pay period and BLS counts worksites covered by unemployment insurance during the quarter, so the numbers are not directly comparable and either can be the larger.
