There are two limitations on the data in the study. In many instances, regional or national data were used to show relevant trends in both production and utilization of fluid milk and milk products. Discrepancies should exist only to the extent that these data or the selected months for which they were collected fail to portray Florida conditions. A second limitation arose due to the refusal of a relatively few firms to provide all or a part of the information requested. In the presentation, appropriate notations are made in tabulations which do not include all firms or total product volumes in a particular milk marketing area or other classi- fications. Review of Literature The many aspects of dairy marketing have provided a wide and diverse field for economics research throughout the United States. Workers in the principal dairy states in the Northeast, Midwest and Central regions have published the largest number of reports9/ During the past ten years several valuable economic studies of problems in dairy marketing in the South have been reported. Very little dairy marketing research was reported in Florida during the 1950's or at any other time in the past. McPherson and Luckey,.ia/: using data from the 1939 and 1949 United States censuses of agriculture, reported trends in the production of milk in Florida by counties. No attempt was made to identify and relate market and supply areas. They did anticipate many of the changes which have since occurred in the technology of milk production and marketing. However, due to the insufficiency of available data, they could not project the probable effects of such changes. The market structure and degree of competition among dairy processing firms in twenty-six counties in South Florida were reported by Brownll/ in 1956.
