About this ranking

Number of establishments with paid employees in mining, quarrying, and oil and gas extraction (NAICS 21), from the U.S. Census Bureau County Business Patterns.

County Business Patterns: establishments (single physical locations, not firms) with paid employees during the pay period including 12 March. Excludes the self-employed and businesses without employees (nonemployer_establishments_*), government employers, crop and animal production, rail transportation, the Postal Service and private households. Establishment counts are not perturbed; the noise Census adds since 2017 applies to employment and payroll, which are not served here. Published about 18 months after the reference year.

Every value in the ranking comes from the same publisher and the same period, so the states are compared on one definition. 1 states with data in other periods have no value for 2021 and are left out rather than filled from another source. Equal values share a rank.
