“It is a stark reminder to the government to stick to their promise to get net migration down to the tens of thousands by the end of this Parliament.”
Overall about a quarter of births in England and Wales were to mothers born overseas.
But in London, for centuries home to new arrivals in the country, the proportion is far higher.
The new figures, released following a question tabled by the Tory MP Nicholas Soames, show that in 2010 there were 86,111 births where one or both parents were foreign-born – 64.7 per cent of the total.
The highest proportion (84.1) was in the east London borough of Newham, a traditionally poor area that will be the site of much of the Olympic Games.
More than three-quarters of babies also had foreign-born parents in Westminster (81.2 per cent of the total) and Brent (81.9).
The lowest proportions of births to foreign families were recorded in Havering (24.4 per cent) which borders Essex in the north east of London, and the more affluent south-eastern borough of Bromley (33.3 per cent).
