Origin in the former Soviet Union

The Personal Records Database (BRP) registers the country of birth at the time of birth. Some of these countries no longer exist. This also applies to the former Soviet Union, which broke up into several countries in the 1990s. For municipal residents whose country of birth (or that of their parents) is the Soviet Union, the birthplace was taken as the basis for their country of origin according to the current country borders. For approximately 95 percent of those of former Soviet origin, the country of birth corresponds with a current country, or the information about place of birth is sufficient to allocate a current country. For the remaining persons, current countries have been allocated on a pro rata basis.
