Methodology
Industry categories follow the U.S. Census Bureau's NAICS (North American Industry Classification System) 2-digit sector codes. Each employer in PlainWorker is assigned a sector based on the NAICS code reported in the OSHA inspection record. Where an employer appears across multiple inspections with differing NAICS codes, we use the most recent classification on file.
Industry aggregates (employer counts, total inspections, total penalties) sum across every tracked employer within the sector. The "Average Penalty per Inspection" metric is weighted by inspection count, not by employer count, so larger employers with many inspections carry more weight. Categories without any tracked employers are excluded. Data refreshes monthly from the Department of Labor's public enforcement database.
