-90- populations, are not available in current literature. Development of such measures was beyond the scope of their study. Hence, there appeared to be little alternative other than projecting fluid milk products de- mand as a function of population increase in Florida to 1970. This method should give a satisfactory estimate if the statements of Mehren and Daly are accepted that (1) per capital demand for food generally is related to population at a ratio close to unity59/ and (2) per capital requirements for dairy products should experience little change to 1975.60/ The model used for projecting demand for fluid milk products in Florida in 1970 is stated below: Dfmp ( t)(Cp ) where: Dfmp demand for fluid milk products, Pt = estimated Florida population in 1970, and Cpe = consumption per capital of fluid milk products. Fitting acceptable figures for population and consumption rates to the equation gives an estimate of the total needs for fluid milk products for the State as a whole. Since most dairy farmers and pro- cessing and distributing firms produce and/or market their products in a specific market area, it is also desirable to estimate the demand for each market area. Separate estimates can be made for each area, the sum of which equals the total demand projected for the State as a whole. Using this method it is assumed that differences in present per capital consumption rates in each area will remain constant. Also, the ratio of population growth in each area will be the same from 1960 to 1970, as from 1950 to 1960, if estimates of area population are not available. Estimated Florida Population, 1970 The population of the State of Florida in 1970 has been estimated by Webb61/ at 6,500:000 and by Arthur D. Little, Inc.62/ at 7,142,000. 59/ N. R. Collins and G. L.
