The activity of state statistics throughout the revolutionary period of 1917 is uncharted territory in the history of Russian statistics. Using documents from the State Archive of the Russian Federation, the authors examined for the first time the last year of the Central Statistical Committee. Unlike other state structures of the previous government, it was not dissolved after the events of October 1917 and continued to operate after the Soviet government moved to Moscow.

The article contains information on the first «Soviet» Head of the Central Statistical Committee of the Commissariat of Internal Affairs V.A. Algasov and outlines the work of Professor M.A. Sirinov, who was offered a position of the Head of the Central Statistical Committee by the People’s Commissar of Internal Affairs G.I. Petrovsky. Archive records helped establish the fact that both the authorities of the Central Statistical Committee and some statisticians came up with an idea of founding a new statistical service based on the Central Statistical Committee and gubernia (provincial) statistics. The authors revealed the role of V.V. Stepanov in relocating the Library of the Central Statistical Committee to Moscow. The article describes the clash of opinions that preceded the establishment of the Soviet state statistics, to be specific the inauguration of the RSFSR Central Statistical Board, which was envisaged to be an independent body, not subordinate to any agency, to ensure the independence of the country’s statistical service.
