Mongolia Civil Registration

Civil Registration
The Central Bureau of Statistics began civil registration in 1921. This early system of civil registration was not universally enforced and does not cover a large percentage of the population. It was replaced by a new universal system in 1951. Records before 1951 are located at the National Archives of Mongolia in Ulaanbaatar. Records from 1951 and later are at the National Center for Registration of Information, Ulaanbaatar.

The following information may be found in these records:
