  • The 2012-based national population projections are published in two parts. The first part was published on 6 November 2013 and included the principal projection and nine variant projections. This second release includes seven further variant projections. This includes some special case scenarios.

National population projections are available by age and sex for the UK and its constituent countries. They are based on the annual mid-year population estimates for 2012 and a set of underlying assumptions of future levels of fertility, mortality and net migration.

The projections are not forecasts and do not attempt to predict the impact that future government policies, changing economic circumstances or other factors might have on demographic behaviour. They provide an indication of the impact that changes in demographic patterns might have on the size and age structure of the population in the future.

Projections become increasingly uncertain the further they are carried forward and long-term projections should be used with caution. To help understand the uncertainty, a number of variant projections are produced based on alternative demographic scenarios. The 2012-based principal projection along with nine variant projections, were published by ONS on 6 November 2013. This release includes a further seven variant projections.

You can easily access the detailed reference tables from this release (and the November release) by using the NPP interactive table download tool.

National population projections are used as a common framework for national planning and policy making in a number of fields such as fiscal sustainability, health, education and state pensions policy. They also provide the base for other products such as subnational population projections and household projections, which are widely used for resource allocation and planning. Further information on the fitness for purpose of the population projections can be found in the summary quality report for national population projections (109.5 Kb Pdf) .
