Migration is a complex issue and to fully understand it we need to consider all information.
Our best assessment shows around 280,000 more people coming to the UK than leaving in 2017, so net migration has continued to add to the UK population.
Net migration has fallen following record levels in 2015 and early 2016, and has been broadly stable since. This is similar to the level recorded in year ending September 2014. Underlying this, immigration has remained broadly stable at around 630,000 and emigration has shown a gradual increase since 2015 and is currently around 350,000.
Our assessment is that net migration has been broadly stable over the last year. Although the Long-Term International Migration (LTIM) estimates show an increase in net migration over the latest year, this is due to an unusual pattern in the estimates for student immigration in 2016, which was not seen in other sources and which our quality work suggests is an anomaly.
Summary of the latest official long-term international migration statistics for the UK for the year ending December 2017 published by the Office for National Statistics (ONS). Data are available from the Home Office and the Department for Work and Pensions (DWP) for the year ending March 2018. This release includes corrections to data for year ending September 2017 and smaller corrections to year ending June 2017. These corrections did not affect the core messages from last quarter’s release.
This is the final report, in a series of six, being published in response to an increased user need for data about the people who may be most likely to be affected by the UK’s decision to leave the EU.
There are many sources of official statistics about international migration to and from the UK, each valuable in its own right in measuring particular aspects of international migration. This note outlines the differences between the data sources and points to more detailed articles regarding this.
