The area frame must be used to conduct an annual study of acreages. yields and livestock and. thereDy. ultimately contrib­ ute to the agricultural census. (6J Efforts to conduct the agricultural census. either with the traditional frame, i.e. the lists of villages. or with the area frame. i.e. areal ~~taps. The complete fulfilment of all above mentioned tasks calls for considerable human and material resources. VI-PROJECTIONS UNTIL THE YEAR 2000 The proposed pi' an wil 1 no doubt satisfy minimum require­ ments in basic agricultural data. Yet, the compilation of sta­ tistics involves continuous and evolutive work. for this reason, in the years following the plan, efforts will have to concetrtr-at.e on r-efining and supplementin<J d·ata cot lected in p..-e­ vious year-s and updating data which no longer reflects existing conditions.
