Sáng số dân số Ottoman năm 1914

The 1914 Ottoman census was published as the Memalik-i-Osmaniyyenin 1330 Senesi Nüfus Istatistiki. According to the introduction, the statistics were derived from data collected during the 1905–06 Ottoman census, adjusted to reflect demographic and territorial changes.

The 1914 census data reflected major changes in the territorial boundaries and administrative divisions of the Ottoman state. The 1914 Ottoman general election provided a significant source of population data. The Empire's total population in the census was recorded as 18,520,015. The grand total for 1914 showed a "net gain" of 1,131,454 people from the 1905-06 Ottoman census survey. The data reflected the loss of territory and population in Europe due to the Balkan Wars, as the total net gain within the Ottoman state’s population was 3,496,068.

The census underestimated non-Muslim populations. For example, in Diyarbekir, the Armenian population was reported at 73,226 in the 1914 Ottoman census, but in September 1915, Reshid Bey announced that he had deported 120,000 Armenians from the province.
