In its summary the report stated that "over 55,000 parcels of property in 80 counties were studied, representing some 20,000,000 acres of land and mineral rights..." It found that "41% of the 20 million acres of land and minerals...are held by only 50 private owners and 10 government agencies. The federal government is the single largest owner in Appalachia, holding over 2,000,000 acres." The study found that the extractive industries, i.e., timber, coal, etc., were "greatly underassessed for property tax purposes. Over 75% of the mineral owners in this survey pay under 25 cents per acre in property taxes." In the major coal counties surveyed the average tax per ton of known coal reserves is only $.0002 (1/50th of a cent).
