Excerpts from the report: The retail prices used in this report are those obtained by the Bureau of Labor Statistics. The farm prices are principally those published by the Division of Crop and Livestock Estimates of this Bureau. Farm-to-retail price margins as used in this study represent all charges between the farmer and the urban consumer. These charges represent varying amounts of transportation, processing, and marketing. For example, amounts of transportation vary from the trucking of vegetables from nearby market gardens to the city to the shipment of many localized crops across the entire country. Amounts of processing vary from practically none at all on such foods as eggs and potatoes to complicated and extensive processing, like the canning of corn and the baking of bread. Costs of city wholesale and retail marketing also vary from commodity to commodity, from city to city, and from one dealer to another. The period covered in this report is from 1913 to 1935. Farm prices, retail prices, and the farm-to-retail price spreads are given for each year in the period for which the necessary price data are available. Tables 10 to 42, pages 34 to 66, show the retail value, the equivalent farm value, the actual margin per retail unit, and the farm value as a percentage of the retail value for each food or group of foods. The methods or calculation are discussed in sections that precede the tables. The annual expenditure for the 58 foods by a workingman's family has also been estimated for each year during the period 1913 to 1935.
