Estimates for UK immigration, emigration and net migration, year ending June 2012 to year ending December 2024. These are official statistics in development. To access the most up-to-date data for each time period, please use the most recently published dataset.

Data exploring the overview of migrants in the UK labour market.

Annual mid-year data on internal migration moves for England and Wales, by local authority, region, single year of age, five-year age group and sex. Data on internal migration moves between local authorities and regions and internal migration moves into and out of each local authority in England and Wales. Also including a lookup table listing each local authority in England and Wales, the region it is located within, its local authority code and region code.

2011 Census internal migration statistics for the UK give estimates that classify people and households in areas within the UK and those having moved from each area to elsewhere within the UK in the year preceding the Census.

United Kingdom UK: Net Migration data was reported at 900,000.000 Person in 2017. This records a decrease from the previous number of 990,000.000 Person for 2012. United Kingdom UK: Net Migration data is updated yearly, averaging 174,003.000 Person from Dec 1962 (Median) to 2017, with 12 observations. The data reached an all-time high of 2,030,075.000 Person in 2007 and a record low of -97,495.000 Person in 1982. United Kingdom UK: Net Migration data remains active status in CEIC and is reported by World Bank. The data is categorized under Global Database’s United Kingdom – Table UK.World Bank.WDI: Population and Urbanization Statistics. Net migration is the net total of migrants during the period, that is, the total number of immigrants less the annual number of emigrants, including both citizens and noncitizens.

This dataset contains information from the Office for National Statistics internal migration data for Wales, showing the origin and destination of each migration flow by sex and broad age group between each of the local authorities in Wales and also the UK countries. Data for flows to and from Scotland and Northern Ireland (and hence the UK as whole) prior to 2011-2012 are not available on this origin-destination basis, although from 2011-2012, the whole of the UK is covered. Data are available split by sex for 2011-2012 onwards only, prior to that data are only available for persons. Note that data for Wales as a whole will not be the sum of individual local authority data as moves between local authorities within Wales will not contribute to the flows into or out of Wales.

The 2002 Yearbook of Immigration Statistics is a compendium of tables that provide data on foreign nationals who are granted lawful permanent residence (i.e., immigrants who receive a “green card”), admitted as temporary nonimmigrants, granted asylum or refugee status, or are naturalized. The Yearbook also presents data on immigration enforcement actions, including apprehensions and arrests, removals, and returns.

This release replaces the previous annual and quarterly publications Control of Immigration Statistics and the annual British Citizenship, following a public consultation. Each topic now has its own entry, links to these related reports can be found under the "additional links" section. There are a range of measures that can be used to understand trends in immigration to the United Kingdom for work, for those people who are subject to immigration control. These include: issues of visas for entry clearance, providing information about those intending to come to the United Kingdom for work; work-related admissions data, providing information on migrants at the border; number of people allocated national insurance numbers, giving an indication of migrants entering the labour market; and estimates on non-EU immigration from the International Passenger Survey on migrants intending to stay for at least a year for work purposes. In addition, grants of (in-country) extensions of stay for work purposes provide information on migrants in-country, while work-related grants of settlement provides a measure of longer term migration.

Introduction

The 2023 mid-year estimate (MYE) is the current official estimate of the population for local authorities in England and Wales. Estimates are produced annually by the Office for National Statistics (ONS) and the 2023 MYE was published on 15 July 2024.

Comparison to previous MYE data

The previous MYE series (for the period 2012-2020) starts with the 2011 census estimate. Each subsequent year’s population is calculated by adding estimates of births, deaths and migration to the previous year’s population. The 2021 MYE represents a break in this series as it uses the 2021 census as its base.

The ONS revised the 2012-2020 MYE series to bring it in line with the 2021 MYE, so that comparisons could be made between between this series and the previous series. The values plotted on the chart are the revised values of the previously published estimates for 2011 to 2022, together with the estimates for 2023.

Key Points

• London’s mid-2023 population was 8.945 million
• London’s population increased by 76,300 persons compared to the previous mid-year value
• Components of change were as follows:
• 105,100 births and 53,500 deaths (natural change of 51,600)
• Net domestic migration was an outflow of 129,200
• Net international migration was an inflow of 154,100

Population Change

London’s 2023 population was 8,945,310. The first chart below shows the 2023 MYE in the context of previous estimates. There is an uptick after a temporary decrease in population which we attribute to the COVID-19 pandemic.

Components of Change

Births, deaths and migration form the components of population change.

The 2023 MYE value for births was 4% lower than that in 2022, and for deaths 3% higher. The consequent value for natural change (births - deaths) was 10% lower than in 2022.

At -129,000, the value for domestic migration (migration within the UK) was nearly 3% higher than the 2022 value, so still significantly lower than the peak net outflow during the COVID-19 pandemic of -186,000. An outflow of domestic migrants from London is normal and this has been the case each year for the last two decades. This flow is partly because many international in-migrants initially settle in London before moving out to other parts of the UK. The second move in this sequence is counted as a domestic migration.

There has been a marked change in immigration since 2021. This can be attributed to the end of free movement for EU nationals, easing of travel restrictions following the COVID 19 pandemic, and the war in Ukraine. At over 150,000, the 2023 MYE value for London’s net international migration was more than 18% higher than 2022, and represents a considerable increase from 78,000 in 2021.
