Commenting, Lord Green of Deddington, Chairman of Migration Watch UK, said:
“This is an important piece of work from a significant institution. What it shows is that the economic benefits of continued mass immigration are trivial when set against the wider costs of an extra population of the order of just under four million.
Specifically, it provides clear evidence that any advantage from high levels of immigration over the long term amounts to less than 1% of GDP per capita even after fifty years.
The NIESR rightly point out that this does not capture the costs of higher immigration resulting from, for example, increased congestion or the potential social impact.
The case for mass immigration, if there ever was one, is blown out of the water.”
