The populations of all regions within England are projected to grow by mid-2028.
All regions are projected to have a greater proportion of people aged 65 years and over by mid-2028.
The East Midlands is projected to be the fastest-growing region, increasing 7% by mid-2028.
The three northern regions are projected to grow at a slower rate than all other regions in England over the next 10 years.
"Over the next decade, the population of most areas is set to continue growing, particularly in the south and Midlands. Our projections also show the share of people aged 65 years and over will increase almost everywhere. This information is particularly important for anyone planning local services – for example, opportunities and services for older people."

Over time, England's population is projected to age, meaning that a higher proportion will be in older age groups. More detail on this is included in the national population projections bulletin.
A common measure of ageing is the proportion of people aged 65 years and over. In England as a whole, this is projected to increase from 18.2% to 20.7% of the total population between mid-2018 and mid-2028. This is the continuation of a trend seen in the population estimates. The proportion is also projected to increase for all regions and local authorities, with the exception of Coventry where there is a slight reduction.
An alternative measure of ageing is the old age dependency ratio (OADR), defined as the number of people of State Pension age (SPA) per 1,000 people of working age. Working age covers all people aged from 16 years up to State Pension age. Note that being over SPA does not necessarily mean someone is retired, nor are all working age people in employment.
By 2028, the State Pension age will rise to age 67. As a result, the OADR in England is projected to fall from 293 in mid-2018 to 287 in mid-2028. However, at local authority level around a third of areas see a rise in OADR over this period.
After mid-2028, almost all areas are projected to have an increasing OADR up to the end of the projection in mid-2043. This reflects the continued ageing of the population during a period in which no more rises in State Pension age are scheduled.

- Old Age Dependency Ratio (OADR) is defined as the number of people of State Pension age (SPA) per 1,000 people of working age. Working age covers all people aged from 16 up to State Pension age. Under current legislation, the SPA in mid-2028 and mid- 2043 will be 67 years old for both sexes.

The interactive population pyramids (Figure 2) allow you to explore the results of the 2018-based population projections for local authorities, counties, regions and England as a whole. By choosing the name of an area you can see how the size and age structure of its population is projected to change. You can create age groups by highlighting your desired ages and can also compare two areas at once.

The East Midlands is projected to be the fastest-growing region in England, growing by 7.0% between mid-2018 and mid-2028
The population of England is projected to increase by 5.0% over the next 10 years, from 56.0 million in mid-2018 to 58.8 million in mid-2028. By mid-2043, the population of England is projected to be 61.7 million. More information on this is available in the 2018-based national population projections. The population of every region in England is also projected to increase by mid-2028.
The East Midlands is projected to be the fastest-growing region in percentage terms; its population is projected to increase by 7.0% by mid-2028, an increase of 334,000 people. Regions in the north are projected to grow at a slower rate than regions in the Midlands and south. The North East is the region with the slowest projected population growth, 2.3% (61,000) by mid-2028.
London is projected to be the largest-growing region in absolute terms; its population is projected to increase by 434,000 people by mid-2028. However, although it was the region with the fastest-growing population in the 2016-based projections, it has dropped to fifth place in the 2018-based.
This can be explained by two factors. The 2016-based projections used internal migration trend data that included some years with lower levels of net internal out-migration from London, years that are no longer used in the 2018-based projections. There have also been higher levels of internal out-migration from London to the rest of England resulting from the improved methodology for estimating internal migration. More information about this methodology change can be seen in the 2018-based methodology report.

What causes population change?
Population change is the result of:
- natural change – the difference between births and deaths
- net migration – the difference between the number of people moving into and out of an area
Migration is further divided into:
- within UK migration – the movement of people within the UK, including between the four countries of the UK and also between areas in England
- international migration – the movement of people into and out of the UK
The balance of factors underlying population change varies by region.

The dynamics of population change vary by region. In some areas – for example, the South East – natural change, net within-UK migration and net international migration are all positive. However, in the North East and the South West, the growth rate is slowed down by negative natural change, meaning more deaths than births. Conversely, although London is the only area with a net outflow of migrants to the rest of the UK, this is more than offset by high net international migration and high positive natural change.
There is also a relationship between different components of population change. For example, London's high levels of natural change reflect a young population where there are many births but few deaths. However, at a slightly older age many people leave London for elsewhere in England, often now with children, contributing to the large net within-UK migration outflow.

All statistics in this bulletin are from our main (principal) subnational projection. However, we have also published a range of variant projections. These include:
a high international migration variant
a low international migration variant
an alternative internal migration variant
a 10-year migration variant
The high and low international migration variants assume either higher or lower levels of net international migration to England as a whole, but the proportional distribution at local authority level remains the same. The result is that all areas see correspondingly higher or lower population totals, with areas that have high levels of international migration in the principal projection (especially parts of London) seeing the greatest difference.
There is often debate around how many years of data should be used to inform the projected population change at local level. In general we use five years of data, but we have used just two years of data for internal migration in the 2018-based projections. This is because we only have two years of data for internal migration available using our current method.
We have produced the alternative internal migration variant, which uses five years of data for internal migration: two using the new method and three using the old method. We have also produced a 10-year migration variant where all migration trends (internal, cross-border and international) are based on 10 years of data.
The pros and cons of using different numbers of years of input data are complex. More information and a comparison of the results of the principal projection, the alternative internal migration variant and the 10-year migration variant are discussed in our article on the Impact of different migration trend lengths. However, you can explore the different results for your area in the interactive Figure 5.

Datasets | Released 24 March 2020
This release includes:
a range of datasets containing all the projections data; this includes summaries and detailed data, as well as projected population by components of change
supporting documentation to help you understand how the projections are produced
Population estimates provide statistics on the current size and age structure of the population in the UK at country, region, county and local authority level. They are the official source of estimated population size in between censuses and inform a wide range of National Statistics.
Population projections provide statistics on the potential future size and age structure of the population. They are based on past trends and assumptions of future levels of births, deaths and migration. They do not incorporate local development plans, but instead provide a baseline, which can be combined with local knowledge as required.
Variant projections are based on alternative assumptions of fertility, mortality and migration to those used in the principal projection. Each variant provides an alternative set of plausible projections that users may find helpful. They provide an indication of uncertainty but do not represent upper or lower limits of future demographic behaviour.
Components of change
Components of change are the factors that contribute to population change. This includes births and deaths (commonly referred to as natural change) and net migration. Migration includes movements of people between England and the various countries of the world (international migration), the other countries of the UK (cross-border migration) and between local areas within England (internal migration).
This is 30 June of any given year.
Usually resident population
Projections estimate the "usually resident population". This is the standard United Nations definition and includes only people who reside in a country for 12 months or more, making them usually resident in that country. As such, visitors and short-term migrants are excluded.

The 2018-based subnational population projections provide statistics on the potential future size and age structure of the population in England at region, county, local authority, clinical commissioning group and NHS England region levels. They are used as a common framework for informing local-level policy and planning as they are produced in a consistent way. They are also used in the production of the 2018-based household projections for local authorities, to be published in early summer 2020. This publication supersedes the 2016-based projections.
The projections take the mid-2018 population estimates, published on 26 June 2019, as their starting point. The projected local authority populations for each year are calculated by ageing on the population from the previous year, applying local fertility and mortality rates to calculate the number of projected births and deaths, and then adjusting for migration into and out of each local authority.
The total projected population for England is also constrained to the 2018-based national population projections for England, by single year of age and sex, for each year of the projection.
In these projections we have incorporated two changes. The first is to treat prisoners as a special population group and the second is to include improved estimates of internal migration. Further information on these changes and on the methodology used to produce the subnational population projections is in the 2018-based methodology report.
More quality and methodology information on strengths, limitations, appropriate uses, and how the data were created is available in the Subnational population projections QMI.
Proposed timing of next projections
Following the publication of the subnational population projections, we will publish the 2018-based household projections for local authorities in England, in early summer 2020.
We usually publish population projections every two years. However, we are currently proposing not to produce 2020-based projections, which would theoretically be published in autumn 2021 for the national projections and spring 2022 for the subnational projections. This is because the first 2021 Census results are also expected in spring 2022; we therefore propose that the next round of projections will be based on 2021, enabling them to use the updated base population that the 2021 Census results will offer, and also a revised back-series of earlier years of input data. This approach would also apply to our household projections.
At this stage, this is not a definitive policy and we cannot be certain of exact timings. Factors that will affect our plans include how different the 2021 Census results are from the current population estimates and our evaluation of the causes of any differences. However, we aim to produce national population projections using a mid-2021 population base by around the end of 2022.
We would welcome any feedback on this proposed approach – please let us know your thoughts at firstname.lastname@example.org. Further updates on the timing of future projections will be communicated in our quarterly Migration and Population Statistics Newsletter. To sign up to this, please contact us at email@example.com.
Transformation of population statistics
It is our mission to provide the best insights on population and migration using a range of new and existing data sources to meet the needs of our users. Our ambition is to deliver a fully transformed system by 2023, making regular improvements to our statistics along the way as more administrative data become available. We will rigorously quality assure new methods and share the impact of any changes made. The Transformation of the population and migration statistics system: overview gives more information on this work. The resulting improvements will also be incorporated into future sets of population projections.Back to table of contents
Subnational population projections are produced in a consistent way across all areas and use a robust methodology so that they are relevant to all types of users. They are used in a number of ways, including: for local planning of health, education and other service provisions; as a basis for household projections; and as a basis for projections produced by other organisations. Dependent on timing of central government planning rounds, they are also sometimes used in the assessment of local authority needs and the funding formula.
Since projections are produced in a consistent way, they can be used as a common framework for informing local-level policy and planning; local areas are advised to supplement them with any local information they have.
The assumptions used in the subnational population projections are based on past trends. However, demographic behaviour is inherently uncertain, so projections become increasingly uncertain the further they are carried forward. This is particularly so for smaller geographical areas and detailed age and sex breakdowns. In the longer-term, demographic patterns are increasingly likely to differ from recent trends. This bulletin focuses on the first 10 years of the projections, up to mid-2028. The data files published with this release include projections going forward 25 years to mid-2043.
It is currently not possible to calculate projections for any further breakdowns such as ethnicity, marital status or lower-level geographies, because of limitations in the availability of data and the lack of a robust methodology required for such projections.
The projections are not forecasts and take no account of local development aims, policies on growth, capacity to accommodate population change, or economic factors that could impact the population in the future. As with the national population projections, they also do not try to predict any potential demographic consequences of future political or economic changes, including the UK's withdrawal from the European Union.
There is already a margin of error in the underlying input data used in the projections, for example, estimates of the current population and past migration flows. In addition, our assumptions about the future cannot be certain as patterns of births, deaths and migration are always liable to change and can be influenced by many factors.
In most cases, each set of projections is superseded when the next scheduled release is published. However, should there be cause to revise a specific set of projections – for example, because of an error in production – the policy on revisions is outlined in the Quality and Methodology Information report.
The subnational population projections Quality and Methodology Information report helps users to understand the strengths and limitations of the data and the suitable uses for the data. It will also help users to reduce the risk of misusing the data.Back to table of contents
