Approximately how many UK citizens are living or working abroad at any given time?

The estimated number of UK citizens living or working abroad at any given time is roughly 1.5 million. This figure reflects the considerable scale of international migration, which encompasses various factors such as education, employment opportunities, and lifestyle choices that lead individuals to settle in different countries temporarily or permanently. This number is supported by government statistics and various studies focusing on expatriate populations, providing a realistic understanding of the diaspora.

The choice of 1.5 million takes into account a range of demographics, including professionals, students, and retirees, making it a well-acknowledged estimate used in discussions surrounding expatriate communities. This estimate is critical for various sectors, including insurance, as policies may need to account for the health and travel needs of these citizens abroad.
