There are parts of Britain where more than half of jobs are held by workers who were born overseas

In Newham – the East London borough hosting the 2012 Olympics - almost seven in every ten jobs are filled by workers who were not born in Britain – or 65,100 out of 93,700 posts. Many of the jobs are on the Olympic site itself. The number of British-born people in Newham who are not in work is 25,600. This is a combination of the unemployed and those classed as economically inactive, such as students and the long-term sick. There are six local authority areas where more than 50% of the jobs are filled by migrant workers – and a further 18 where those born outside Britain take up more than one in every three jobs. Outside London, the areas where the biggest proportion of jobs are taken by immigrants are Slough, Leicester, Luton, Reading, Cambridge, Manchester and Oxford. Crawley, in West Sussex, and Elmbridge, in Surrey, are also at the top of the list.
