Add as preferred source on GoogleRevised ONS data reveals higher net immigration to Britain in 2023 and increased emigration of Britons, reshaping previous estimates.
LONDON (Reuters) -Net immigration to Britain peaked in 2023 at a higher level than previously thought, and a far greater number of Britons left the country in subsequent years, revised official data showed on Tuesday.
Britain's Office for National Statistics said most of the revisions were due to using labour ministry data that better captured the presence of British nationals than earlier surveys of travellers at ports and airports.
The number of British nationals who moved to Britain between 2021 and 2024 was twice previous estimates and the number of Britons who emigrated was three times higher than before.
Revisions to the number of non-British, non-European Union nationals were small and the figures also showed that fewer EU nationals had left than previously estimated.
Political discourse in recent months has been dominated by high levels of non-EU immigration - both legal and illegal - with the Labour government setting out various policies to cut down arrivals.
Below are the key facts and figures from the revised data which covered the pandemic period:
* New ONS estimates show overall net immigration to Britainpeaked at 944,000 in year ending March 2023, higher than itsprevious estimated peak of 906,000 in the year to June 2023 * The estimate for net immigration in the year to December2024 was revised downward to 345,000 from 431,000, largely dueto higher emigration by British nationals * Cumulative net immigration between 2021 and 2024 inclusivewas around 97,000 lower than previously thought * Cumulative net emigration by British nationals from2021-2024 was revised up to 412,000 from 44,000 * Cumulative emigration figures for British nationals overthe 2021-2024 period was revised up from 343,000 to 992,000 * Cumulative immigration figures for British nationals from2021-2024 was revised up from 317,000 to 623,000(Reporting by Muvija M; editing by David Milliken)
Emigration is the act of leaving one's resident country with the intent to settle elsewhere. It contrasts with immigration, which is entering a new country.
The Office for National Statistics (ONS) is the UK's largest independent producer of official statistics, providing essential data on the economy, population, and society.
Immigration data is crucial for understanding demographic changes, economic impacts, and social dynamics within a country, influencing policies and public services.
