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 number of different measures that can be used to monitor numbers of people coming to the United Kingdom for study.
For those students who are subject to immigration control, administrative information is available on student visas and visa extensions, as well as records of students admitted. The International Passenger Survey (IPS), run by the Office for National Statistics (ONS), provides estimates of all students arriving in the UK, with the ONS migration statistics focussing on those who intend to stay for a year or more. Research into students has also been published, for example Migrant Journey Analysis that involved linking records to give a more complete picture as to what happened to a group of students over a five year period.
These various statistics and research can appear to give different pictures of student immigration. Often this is because the latest data for different measures cover different time periods. In addition, they also count different aspects of the immigration process, with some showing intentions or permissions, whilst others show actual events.
