Entwicklung der Agrarproduktion in den USA und der UdSSR bis 1982

Die Quelle gibt folgendes an: "Growth rates are measured in indigenous currencies. Because of wide fluctuations in annual farm output, we calculated the Soviet data using a three-year moving average for the base and terminal year in each period. Farm Outout includes all crops produced during the year except hay and pasture, hayseeds, pasture seeds, and overcrop seeds. It also includes the net production of livestock other than draft animals. Net livestock production is the gross production of livestock products and inventory change minus the value of products (grain, potatoes, vegetables, and milk) fed to livesetock and minus the value of hatching eggs. These deductions were made to avoid counting feed crops twice-in the production of both livestocks and crops-and to avoid counting hatching eggs as part of poultry meat production as well as of egg production."
