This report deals specifically with performances on 14 types of commercial family-operated farms. It is another in a series which presents information on shifts in production and changes in farm organization, practices, methods and efficiencies in production, mechanization, technological developments, prices, costs and returns on farms by type, size and location. It brings to date the summary information on the 14 types of farms presented in F.M. 55, "Typical Family-Operated Farms, 1930-45, Adjustments, Costs and Returns," April 1946. The information in these reports are averages of large groups of common types and sizes of farms in designated areas. The information is obtained from well-defined homogeneous groups of farms selected by accepted sampling methods. The averages, therefore, are representative of the operations and returns on the rank and file of specified types of farms.
