were obtained by personal interviews with the manager or representatives of each fluid milk processing plant.- An accounting was made of the utilization and distribution of milk received. These data included: (1) location and capacity of processing and distributing facilities, (2) volume handled by product and by type and size of package, (3) methods of distribution employed and quantity marketed by each method and (4) the volume of sales for each county in which products were distributed. When sales were made to a distributor, the products were shown as sold in the county in which the distributor was located, Information was not obtained from distributors as to whether they sold products in counties other than those in which they were located. Data on the utilization and distribution of milk were obtained in the four administered milk marketing areas partly from records of market control agencies. Additional data were collected by schedules completed during personal interviews with representatives of firms processing and distributing fluid milk products in these areas. In Northwest Florida, data were obtained entirely from interviews with representatives of each dairy processing plant. In each area, data were collected on supplies and utilization of milk for two months--Aprll and October, 1959. April is a month with heavier than normal producer deliveries of milk. October is a month of greater than normal fluid milk sales in most marketss./ The Dairy Division of the Florida State Department of Agriculture provided a summary of the amount and origin by states of all fluid milk products shipped into Florida in 1959. Method of Analysis The data were analyzed on a marketing area basis largely by tabular methods. Firms in each area were stratified into three size groups on the basis of fluid milk sales per day: (1) less than 2,500 gallons, (2) 2,500 to 9,999 gallons and (3) 10,000 gallons and over. Comparisons were made between size groups within each market and for firms of each size in the several marketing areas. The potential demand for fluid milk in Florida markets was projected based on two estimates of expected population and assuming a per capital consumption the same as the estimated consumption in 1959. 2/ For multi-unit firms, each processing plant was treated as an individual firm. 8/This is shown graphically in Chapter V, Figure 21. Furthermore, these months were used so that the data collected would be for the same period as in each of the other state projects contributing to the Southern Region Dairy Marketing Project SM-10 Revised.
