Population projection

The population projection method used by Statistics Finland is a so-called demographic component model where the future number and structure of the population are calculated by age group by means of age group-specific fertility, mortality and migration coefficients. The coefficients are calculated on the basis of population development in the last few years. The projection does not seek to estimate the effect of economic, socio-political regional policy and other such factors on population development.

Statistics Finland's population projection is a demographic trend calculation where population development is assumed to continue as in the last few years. Municipal population projections are made by Statistics Finland every three years.
