The UK population is entering unprecedented times in terms of its ageing structure. We will continue to produce the official population statistics for the UK, and to make better use of existing data sources and to develop new ones where possible by working with others. We aim to provide additional insight into how the UK population are living their lives and how this is changing. This has implications across many areas of society including where people live, family and household structure, fertility and mortality.
Population Estimates and Projections
We produce the official estimates of the UK population:
- population estimates by age and sex for the UK and countries, regions and local authorities within the UK
- population estimates for smaller geographies
- components of population change (births, deaths and migration)
- electoral statistics
- population projections (national and subnational)
- household projections for England
In addition to producing statistics on the UK population, we also build evidence on how the UK population is changing and why it is important. Topics include:
- how the population is ageing
- fertility and mortality
- families and households
- the population by characteristics such as marital status and sexual orientation
- insight into how people are living their lives by key milestones reached in life
Improving the evidence
One of our priorities is to identify which statistics and analysis will be the most helpful for understanding how and why the population is changing; why this is important; and which evidence would be useful to inform relevant policy decisions. We are doing this by forming partnerships with organisations and ensuring that we maximise future opportunities such as the development of the 2021 UK Population Census and future development work incorporating new data sources.
We lead international work to improve the evidence on ageing globally via a United Nations "City Group". Better data on older populations will enable improved measurement of the Sustainable Development Goals.Back to table of contents
