Russian Empire census
The first general census of the population of the Russian Empire in 1897 (Russian: Пе́рвая всео́бщая пе́репись населе́нія Россíйской импе́ріи 1897 го́да) was the first and only nation-wide census performed in the Russian Empire (excluding the Grand Duchy of Finland). It recorded demographic data as of 28 January [O.S. 15 January] 1897. Previously, the Central Statistical Bureau issued statistical tables based on fiscal lists (ревизские списки).
The census revealed the social class, native language, religion, and profession of citizens, which were aggregated to yield district and provincial totals.
The second Russian census was scheduled for December 1915, but was cancelled because of World War I, which had begun during 1914. It was not rescheduled before the Russian Revolution. The next census in Russia only occurred at the end of 1926, almost three decades later.
