Business owners have been the fastest-growing part of the UK labour force since at least 2000. Between 2000–01 and 2015–16, the number of employees grew by 15%, while self-employment (including those operating as a sole trader or as a partner in a partnership) grew by 25% and the number of directors of companies with at most two directors more than doubled. The number of new businesses created in the UK between 2007–08 and 2015–16 was higher than in any other OECD country.
