Running population registrations – including births, marriages, and deaths – were carried out by religious organisations until 1918.

On 26 February 1877, the draft of "Regulations on the General National Census", which was developed by a commission under the Ministry of Finance, was submitted to the State Council; however, it was not discussed there, possibly due to the Russo-Turkish War that occurred from 1877 to 1878.
