Migratory & Seasonal Farmworker Population Estimates
Two interactive maps that display USDA's Census of Agriculture 2012 estimates of the number of crop and animal production workers by county. Estimates also include, for most of the counties, the number of child dependents and spouses not involved with farmwork, complied from the Department of Labor's National Agricultural Workers Survey.
