US: Organic operations concentrated in West, Northeast, Upper Midwest
Northeastern States have the highest share of certified organic farmers, particularly Vermont and Maine, where about 5 to 6 percent of all farmers are certified organic. Organic processors, manufacturers, and other food-handling operations are concentrated around large metropolitan areas, while certified organic livestock operations are located predominantly in the Great Lakes region. The top 10 States for organic farm sales accounted for 78 percent of the total value of all U.S. certified organic commodities sold in 2015. California alone contributed 39 percent of total U.S. organic farm sales.
