Trend in Urban Population.--In numbers of urban residents in 1960, milk marketing areas ranked from smallest to largest were: Northwest, Northeast, Central, Tampa Bay and Southeast (Table 16). The pro- portion of total population classified as urban ranged from 51.3 per- cent in Northwest to 90.1 percent in Southeast Florida. The major consuming group for commercially processed and distributed fluid milk is the urban population. Consequently, Southeast Florida, with over one-third of the State's total population and 40 percent of its urban inhabitants, requires the largest volume of fluid milk to meet consumer needs of any area. Milk marketing areas have become increasingly urbanized.33/ As shown in Table 17, the 1960 urban population of the State was 202 percent of the 1950 total. The greatest increases in urban 33/Changes in definitions of the Bureau of the Census for - classifying population as urban residents occurred in 1950.
