About the statistics
National population projections are calculations of how the population in Norway will potentially develop over time, given different assumptions about fertility, mortality, immigration and emigration.
A population projection is an estimate of the future size and composition of a population, given certain assumptions of future fertility, life expectancy, immigration and emigration. The term projection is used for any estimate of the future population, including less likely ones. A prognosis or forecast is an estimate of the most probable future population size and composition.
Statistics Norway publishes several projections, but the MMM alternative, which assumes the medium level for each component, is what we assume to be most plausible.
The various alternatives and terms used in the population projections are described in the projections report (see link under 'Relevant documentation').

The national population projections are published biennially.
Statistics Norway reports projections to Eurostat and the United Nations, among others.
The population projections utilize aggregated individual-level data on population size, births, deaths and migration from Statistics Norway’s population statistics. The results from the projections are stored in the StatBank at Statistics Norway and as separate files. Aggregated data may be downloaded electronically from the StatBank.
The population projections aim at informing planning and public debate on population issues.
Statistics Norway has produced population projections regularly since the 1950s. Previous population projections can be found here, and in the StatBank.
The most important users of Statistics Norway's population projections are public and private planning bodies at the municipal, county and central government levels, as well as researchers, politicians, journalists and the general public. The projections are also used internally at Statistics Norway, for example as input in macroeconomic models.
The population projections are published in accordance with international standards. The Norwegian figures are more detailed (immigration category, country group and period of residence) than what is commonly published in most other countries.
There are no specific rules regulating the population projections, but the production process of the projections is based in the Norwegian Statistics Act of 2019.
Although there is no separate EU regulation in this field, a collaboration exists between Norway and Eurostat. Eurostat produces population projections for the EU and Norway on a regular basis. These projections differ from those produced by Statistics Norway.
To project the population, assumptions are needed on future fertility, mortality and international migration. After the assumptions are made, the Norwegian population is projected using the cohort component model BEFINN.
The methods used are further described in the projections report (see link under 'Relevant documentation').
The population projections utilize aggregated individual-level data on population size, births, deaths and migration from Statistics Norway’s population statistics. We use data categorized by age, sex, immigrant background and country group of origin for 1 January each year, in addition to figures on births, deaths, immigration and emigration by age and sex.
No samples are used. The projections utilize the whole population in estimations.
The methods used in the population projections are described in detail in the projections report (see link under 'Relevant documentation').
No data are collected specifically for the purpose of making population projections.
At a national level, previous versions of the population projections are comparable. Though country groups are not entirely comparable over time, since the definition and the number of groups have varied.
In comparing results from the population projections to the general population statistics at Statistics Norway, two main differences stand out:
- The projection models project the population from 1 January one year to 1 January the year after. This means that individuals who move between Norway and other countries several times during one year only contribute one move. Consequently, somewhat fewer migrations are used in the population projections compared to the numbers that are published in the general population statistics.
- The age definitions are not the same in the projections and the general population statistics. While the general population statistics use age at time of event (e.g. birth, death or migration), the projections use age at the end of the year. This means that the age-specific rates and probabilities used in the projections – as well as the life expectancy figures – may differ slightly from what is published in the population statistics.
There is marked uncertainty about whether the assumptions used in making the population projections will accurately reflect future demographic trends. Over the past decade, future immigration has proven to be the most difficult component to project. This is also likely to be the case in the years ahead. Fertility and mortality rates can also be very different to what is projected.
Models are simplifications of reality, and as such may only capture a few key mechanisms. There are a multitude of other conditions that will affect population development which are not considered.
Errors in the population statistics system are usually modest in Norway and play a minor role in the projections.
In general, uncertainty increases with time. For more information, see links under ‘Relevant documentation’.
