2010 research found that White Britons (defined as White English, Welsh, Scottish and Irish-born citizens) will be a minority in the UK by 2066 if immigration continued at the current rate. The 50 per cent mark will be passed much quicker among schoolchildren, students and young workers. Foreign-born mothers accounted for a quarter of births in England and Wales. Both Leicester and Birmingham were expected to become "majority minority" during the 2020s. Two London boroughs were already majority non-white in 2001
