Statistical presentation
Data description	Persons who have changed their usual residence (current address) are surveyed. The registration is done at the moment of migration and the total migration is calculated as of 31.12 of the reference year.

Sector coverage	Data on migration concerns a calendar year and include all persons who have changed their current address within the country, address in the country with an address abroad and address abroad with an address in the country.
Statistical concepts and definitions	Migration growth of a given country territory is the difference between the immigration to and emigration from the area during the year. Net international migration is the difference between immigration into and emigration from the country.
