ABSTRACT
Since 1956 the Central Statistical Bureau (TsSU) of the USSR has been publishing the yearbook Narodnoye klwzyaystvo SSSR (The National Economy of the USSR) and other source materials on union and autonomous r~publics, regions, and areas. These publications contain a variety of statistical information, including demographic data, not only for the year in question, but for some past years as well, although with substantial chronological gaps and omissions. For example, an entire period such as 1929-36 is simply omitted. These data are accessible to any scholar. I am neither a demographer nor a historian but my familiarity with mathematical methods has allowed me to perform the necessary calculations routinely used in demography. To make the accuracy of the results verifiable, I have made a consistent effort to explain my calculations. In addition, every variable has several estimates; therefore a possible range of values is also given.
