* Information in the Census of Agriculture is not adequate to precisely identify a farm as a CAFO. Potential CAFOs were estimated based on the livestock type and the estimated number of animals on the farm.
** Farms that qualify as potential CAFOs for more than one livestock type are double counted when summed over livestock types.
