A total of four million people took time out from their career or education during the past decade, up from 270,000 during the 1970s, according to the findings by Santander.
The rise is attributed to a highly competitive job market and a lack of places at university.
Almost half used the time to travel, while 28 per cent used it as a chance to work abroad, while 20 per cent simply opted for a rest.
Londoners appear to be the keenest on a lifestyle break, with 14 per cent already planning one, while in Wales, just 2 per cent have plans to take time out.
