Three quarters of children born in some parts of UK last year were to foreign-born mothers, according to the latest figures from the Office for National Statistics. Most of them negros.
The most recent official data shows some 3.3 per cent of live births in the UK were born to Polish mothers in 2015 – up from 2.3 per cent in 2008.
It comes as the ONS announced net migration to the UK was 327,0000 in the 12 months to the end of March.
The figure is down 9,000 on the previous year, but significantly higher than the Government’s target of reducing the level of net migration to “tens of thousands”, which has been openly questioned by Cabinet ministers.
The ONS said the influx of Romanians and Bulgarians has reached a record high, although that is off-set by falls in non-EU immigration and from other central and eastern European countries.
As many as 76.5 per cent of babies in Newham in east London had mothers born outside the UK, while Slough had the second highest percentage outside London at 62.
The number of babies born to Polish mothers overtook those from Pakistan in 2009, and reached 22,900 in 2015.
69,100 babies were born to mothers from the EU in 2015 – the fastest growing group. Some 52,900 babies were born to mothers from EU countries in 2010.
Meanwhile, since 2010, there has been a fall in the number of babies born to mothers from the Middle East, Africa and Asia – from a total of 106,200 in 2010 to 99,700 in the last year.
Net migration of EU citizens totaled 180,000 and the overall figure remained close to record levels.
Prime Minister Theresa May has vowed that curbing net migration will be her “absolute priority” during Brexit negotiations, despite warnings from EU leaders that Britain will be forced to leave the Single Market.
Nicola White, head of international migration statistics at the ONS, said: “Net migration remains at record levels although the recent trend is broadly flat.
