What the Mining, Quarrying, and Oil and Gas Extraction Sector Numbers Reveal
The Mining, Quarrying, and Oil and Gas Extraction sector (NAICS 21) aggregates 48 distinct sub-industries into one benchmarking unit. At the sector level, the average net profit margin is 2.0% - a figure that is significantly below average. Averages at this tier can mislead because they blend high-margin specialty lines with commodity operators: Support Activities for Mining runs at 7.2%, while other sub-industries inside the same sector operate well below that headline. When you benchmark a business against a sector, always drop one level deeper to the NAICS 6-digit industry that matches your actual operations.
Scale metrics reinforce the story. Census Bureau CBP 2023 records 553,036 employees across 23,360 establishments in this sector, with $411.5B of annual receipts flowing through the IRS SOI filings. The largest employer sub-industry is Support Activities for Mining with 288,339 workers, followed by Mining (except Oil and Gas) at 173,729. Understanding which sub-industries drive headcount helps identify where labor cost trends, wage pressure, and hiring competition will concentrate, all of which feed directly into the profit margin shown above.
