About this ranking

Places from which 1,000 dollars or more of agricultural products were produced and sold, or normally would have been sold, during the census year, 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.
