Changes in costs associated with each level in the fresh and processed citrus marketing channel are examined. The results indicate that more than 60 percent of the retail food dollar spent on fresh grapefruit is associated with activities that occur after the fruit leaves fresh fruit packinghouses. For frozen concentrated orange juice and canned single-strength grapefruit juice the F .O.B.-retail margin was estimated to be 25 and 27 precent, respectively, of the consumers' expenditures. Total citrus bearing acreage has declined 17 percent since 1970-71. Total citrus production has decreased 40 percent since 1979-80.
