Only one out of ten babies in UK are born to mothers of white British origin, according to recent statistics.
Britain's rapidly changing ethnic make-up means white British women are now in a minority on maternity wards in 27 National Health Service (NHS) Hospital trust areas, the Daily Express said.
Across the country as a whole, they still account for 69 per cent of pregnant women receiving hospital care.
But the figures from 150 NHS trusts in England reveal the ethnic diversity in metropolitan areas.
David Coleman, professor of demography at Oxford University, said: "Some ethnic groups have considerably higher birth rates, especially Pakistanis and Bangladeshis. On the other hand, the Chinese and Indian birth rate is lower."
The average birth rate among white British mothers is 1.7 children. For Pakistanis and Bangladeshis it is about three.
