The tendencies in the production per capita during the period are estimated by linear regression and shown graphi­ cally • • Explanatory Notes Definitions of aymbols used in the tables: None, in negllbible quantity (less than one-half of the unit indi­ cated) or entry not applicable. Data not available ~) Data not included in continental, regional and world totals because they are components of country totals, or because they refer to a dlfferent series which should not be included in the totals. To divide the de~imals from the whole number. a period (.) ls used. Crop Areas Figures for cassava crop areas generally refer to the planted area. Yield per Rectare The yield per hectare for individual countrles is computed by divl­ ding total production by the area planted. Totals Because of the scarcity of information from certain countries. some of the tables are not complete. 2. J' . For a number of African countries and Indonesia the data are shown separately for "Fama and Estates" and for "Villages". Generally included under "Farms and Estates" are the crops grown and the livestock kept on estates and farma which are mainly opersted on s commercial basia and sde- quately covered by the annual agricultural surveys. Under "Villages" are included the crops grown and the livestock kept generally under traditional • agricultural conditiona. For Indonesia, "Farms and Estates" indicate large and c01lJlllercial farma; "Villages" indicate small farms. Production per capita Tbe productlon per capita for individual countries for each year ls computed by dlviding total production by the total population. Trend line • In this study the "trend line" is used for the purpose of estimating the production per capita trend during the period 1948-1969 for each of the major cassava producing countries. Tbese trend lines were fitted by the least squares technique. CARIBBEAN ISLANDS AND CENTRAL AMERICA • ... . • , •• 11& • • '" 3.
