The survey was initiated in 1941 and is sponsored annually by the Iowa Agriculture and Home Economics Experiment Station, Iowa State University. Only the state average and the district averages are based directly on the Iowa State survey data. The county estimates are derived using a procedure that combines the survey results with data from the U.S. Census of Agriculture.
