The 1914 Ottoman census was published as the Memalik-i Osmaniyyenin 1330 Senesi Nütus Istatistiki.
[1] The 1914 census lists reflected major changes in the territorial boundaries and administrative division of the Ottoman state.
[2] The grand total for 1914 showed a "net gain" of 1,131,454 people from the 1905-06 Ottoman census survey.
[5][6] As a result of the substantial territorial losses in Europe suffered during the Balkan Wars, the total population of the empire fell to 18,520,016, of whom an even larger percentage than before, 15,044,846, were counted as Muslim, with 1,729,738 as Greek Orthodox, 1,161,169 as Armenian Gregorian, 187,073 as Jewish, 68,838 as Armenian Catholic, 65,844 as Protestant, and 62,468 as Greek Catholic.
[7] The capital, Constantinople (Istanbul) was an important location due to expulsions from Balkan Wars.
