Statistics Norway produces the population projections for Norway. This is one of Statistics Norway’s ongoing tasks and is financed by the central government. Methodology and results are published on Statistics Norway's website.
Population projections are a key tool in both local and national planning. They are also used in other types of economic and demographic projections and are of interest to public authorities, the private sector and the general public.
To project the national population, make assumptions about future fertility, mortality and international migration (immigration and emigration). These assumptions are incorporated into a cohort-component model, which calculates future populations by age and sex at the national level up to and including the year 2100. Immigrants from three country groups, Norwegian-born children with two immigrant parents and the rest of the population are projected as separate groups. Immigrants are also projected by duration of stay, based on when they first immigrated to Norway.
Beyond the publication of results, the project performs empirical analyses of the components (fertility, mortality and migration), development of the methodologies and evaluations of the accuracy of earlier projections.
