Migration within Austria
Internal migration covers all changes of main residency within the borders of Austria. They can be divided into migration flows within and between municipalities, political districts and federal provinces.
Since 2002, migration statistics have been based on administrative registrations and deregistrations of main residencies in the Central Population Register. Changes of residence within the same building are not included in migration statistics, however. Only persons who have registered a main residence in Austria for at least 90 consecutive days are included.
