A revision of the calculations of Soviet national income that hav been presented in previous RAND publications (R-253, R-255, and RM-101). RAND Report R-367-PR, The Real National Income of Soviet Russia since 1928, deflates the current-price accounts to obtain estimates of Soviet national income in "real" terms. To complete the latter study, it was essential to review and revise the current-price estimates for 1928 to 1948, which were published several years ago. This revision examines the large volume of statistical data, and other relevant information, published in the Soviet Union since that time. It introduces a few methodological changes, tending toward greater consistency in the calculations for different years. It also corrects some deficiencies and errors found in the original calculations. With minor exceptions, these recent efforts have confirmed the accuracy of RAND's earlier assessments of Soviet national income and product.
