The Population Register Centre receives notification of changes from civil registry administrators, magistrates, courts, etc. The Population Register Centre processes and checks the data and updates its Population Information System (which until 1 November 1.11.1993 was called the central register of the population). The Population Register Centre sends data on population changes in machine-language format to Statistics Finland on a weekly basis, after updating the system, where the data are edited for statistical use and printed into statistical tables. The statistical unit is migration (not migration). The change to the area is referred to as immigration and moving out of the area is called departure change. The population change data calculated from the statistics on population change differs from the corresponding data in the demographic statistics, because not all migrations have been recorded and the population is corrected on the basis of other data. ##Reliability of Information Information on the place of residence of persons can be obtained in the Population Information System via the notification of moving.
