with all Soviet historiography, reliability of Soviet statistical data varied from period to period. The first revolutionary decade and the period of Stalin's dictatorship both appear highly problematic with regards to statistical reliability; very little statistical data was published from 1936 to 1956 (see Soviet Census (1937)). The reliability of data improved after 1956 when some missing data was published and Soviet experts themselves published some adjusted data for Stalin's era; however the quality of documentation deteriorated. While on occasion statistical data useful in historical research might have been completely invented by the Soviet authorities, there is little evidence that most statistics were significantly affected by falsification or insertion of false data with the intent to confound the West. Data was however falsified both during collection – by local authorities who would be judged by the central authorities based on whether their figures reflected the central economy prescriptions – and by internal propaganda, with its goal to portray the Soviet state in most positive light to its very citizens. Nonetheless the policy of not publishing, or simply not collecting, data that was deemed unsuitable for various reasons was much more common than simple falsification; hence there are many gaps in Soviet statistical data. Inadequate or lacking documentation for much of Soviet statistical data is also a significant problem.
