There are maternity units in Britain in which only 1 in 10 mothers is of white British origin

Just one in ten babies is born to a white British mother in some parts of Britain. The statistics - based on NHS monitoring of the ethnicity and nationality of patients - show a sharp contrast in the backgrounds of new mothers in urban and rural areas. Across all of England's 150 NHS Trusts there were 652,638 deliveries in 2009, around six out of ten of them to women who called themselves white British. Across England 62% of all births in 2009 involved a white British mother. The largest other single ethnic groups were 'other white' - including Eastern Europeans - which made up 7% of births, black (5%), Pakistani (4%) and Indian (3%). Of the rest of the mothers 8% described their ethnicity as 'other' (including mixed-race women) and the remainder were listed as 'not known'. Backbench Tory MP Douglas Carswell said: 'I think we have to face reality and that is if you continue to have mass immigration it's going to have a very significant impact on the demography of our country - and it's going to have a significant impact perhaps on the sort of country that we are.' Recently it emerged that Britain's population growth is outpacing every other country in Europe. Immigration and rising birth rates driven in part by the children of new arrivals - the so-called 'immigrant baby boom' - meant Britain gained more people than anywhere else in Europe. Ministers have proposed forcing non-EU migrants to buy their own private health care for non-emergency treatment on the NHS. David Cameron has pledged to reduce the level of net migration - the number of people arriving minus the number leaving - from the hundreds to the tens of thousands. The Prime Minister has proposed putting a limit on the number of immigrants from outside the EU given work permits for Britain.
