1. At international level, no universally accepted definition for 'migrant' exists, but the UN recommendations for statistics on international migration and on population censuses specifies at least one year as the criterion for change of country of usual residence to define this change as ‘migration’.
2. Under the UN definition, those travelling for shorter periods as tourists and business persons would not be considered migrants. However, common usage includes certain kinds of shorter-term migrants such as seasonal workers .
3. The term 'migrant' is usually understood to cover all cases where the decision to migrate is taken freely by the individual concerned for reasons of 'personal convenience' and without intervention of an external compelling factor; it therefore applies to persons, and family members, moving to another country or region to better their material or social conditions and improve the prospect for themselves or their family.
4. This definition does not include intra-EU mobility of citizens or residents, even though national concepts of international migration may include mobility, as will national statistics on international migration.
