‘Great Gen Z exodus’: Young Britons leaving UK in record numbers over rising cost-of-living

A record number of young people are leaving the United Kingdom, with rising living costs and limited financial prospects driving a sharp rise in youth emigration, according to a new report.According to data from the Office for National Statistics (ONS), between 130,000 and 140,000 Britons aged 20 to 29 emigrated in the year to June 2025—well above pre-pandemic levels of around 92,000 to 95,000 in 2018.The trend signals a major generational shift, with younger adults now choosing to move abroad earlier than previous generations.

‘Great Gen Z Exodus’ report flags shift

The findings are backed by The Great Gen Z Exodus report by The TEFL Academy, which highlights how Britons are no longer waiting until their 30s to relocate.Instead, many are opting to leave in their 20s, driven by changing career priorities and global opportunities.

Cost of living driving decisions

Economic pressure has emerged as the biggest trigger behind the migration wave.

The report suggests that for many young people, moving abroad is increasingly seen as a pathway to a better quality of life.

Majority planning or considering move

The survey findings underline the scale of the trend:

Overall, nearly three-quarters of those leaving the UK are now under 35.

Changing definition of success

Rhyan O’Sullivan, Managing Director at The TEFL Academy, said young Britons are “not running away from the UK, but running toward opportunity.”For many graduates, teaching English overseas has emerged as a practical route to gain international exposure, improve earnings, and build global careers.The report, based on a March 2026 survey of young adults along with labour market and migration data, highlights a broader rethink among Gen Z about stability and success.International mobility, once seen as optional, is now being viewed as essential for financial security and career growth, marking a shift in how the younger generation approaches work and life.
