Injury and enforcement counts include contractor incidents at these mines, per MSHA’s own attribution; employment counts operator employees only, so the two must not be combined into a rate. Mine-level records sit under the operator MSHA lists, which can lag ownership changes. US mines only.

    "Licensed source" names the channel, not a vendor, and says nothing about what the data contains - only that reaching it runs through a commercial licence rather than a public register. "Not published" means no register or filing obligation we know of covers it, which is a statement about disclosure rules rather than about this entity's conduct.
