About this ranking

Land operated by farms in the census year, in acres, including cropland, pasture, woodland and land under farm buildings, as counted by the USDA Census of Agriculture every five years.

Every value in the ranking comes from the same publisher and the same period, so the counties are compared on one definition. Equal values share a rank.
