ABSTRACT
This chapter analyses the demographic and economic effects, assumptions in accordance with the demographic projections from Statistics Norway are chosen. It presents in demographic projections made by Statistics Norway's transition matrix model for population projections named BEFREG. The model takes account of fertility, mortality, internal and external migration in projecting the population by gender, age and municipality, one year at a time, using a cohort-component method. The age composition of immigrants may be quite important for determining the economic effects from immigration, and the large net migration to Norway in the last years is mainly made up of young person’s compared to the Norwegian population as present. Even though the existing analyses provide a lot of information about economic effects from immigration it is possible to increase knowledge about the empirical effects related to different assumptions by a combined use of Statistics Norway's demographic and economic models.
