Thank you for your enquiry regarding EU citizens living in the UK.

Please find the attached excel spreadsheet detailing the ages of EU Citizens and when they arrived in the UK. It has not been possible to directly answer your question split by how long people have been in the UK, but the year of arrival provides information back to 2005.

This data is taken from the Annual Population Survey in 2015. The Annual Population Survey (APS) collects information on year of arrival and reason for immigration. The APS is a sample survey based on households and does not include people living in most types of communal establishments. The Annual Population Survey is a household survey of people in the UK. It covers people in private households, NHS accommodation and students in halls of residence whose parents live in the UK. However people in other communal establishments such as prisons and private care homes are excluded.

The Annual Population Survey has the largest coverage of any household survey with approximately 320,000 respondents.
