tilflyttingsdata

Tilflyttingsdata are statistics about people who move into a specified geographic area during a defined period. They are part of population mobility statistics and are used to measure in-migration, often published for municipalities, regions, or nations.

Tilflyttingsdata are typically collected from administrative population registers or civil registration systems and are compiled by national statistical agencies, such as Statistics Norway (SSB). They usually include the number of in-migrants, the date of registration of the move, the area of origin, and basic demographic characteristics such as age and sex. In some datasets, information on citizenship, country of origin, or education may be available at aggregated levels. The data are generally recorded for a defined time window, such as a calendar year, and may distinguish between permanent moves and temporary relocations.

The geographic scope can vary from local municipalities to larger regions or countries. The data are used to update official population counts, analyze urbanization and housing demand, assess service needs for schools and healthcare, and support planning and labor market analyses. They also underpin population projections and demographic research.

Limitations and considerations include varying definitions of what constitutes a move, the time lag between a move and its recording, and potential under- or over-counting due to registration practices. Privacy and data protection rules, such as anonymization requirements, can affect the level of detail available in public datasets. Tilflyttingsdata are related to other migration measures, including innflytting, utflytting, and net migration.
