Methods
Statistics Iceland assesses migration on the basis of information on changes in legal domicile in the National Registry's Population Register. Migration are counted on the basis of the date of registration in the National Registry, but not according to when the migration took place. It should be noted that there may be some delay in the registration of persons with foreign citizenship who receive a residence permit, and at the same time there may be some delay for those individuals who emigrate from the country.
