There are more British-born people (the ONS definition of “British” in this context) in work today than ever before: 28.1 million, up almost 400,000 since 2015.

Yes, the number of foreign-born workers is up too. It’s around 3.5 million, up from just under 1 million in 1997.

Employment among non-Brits is rising faster than employment among Brits. Does that mean Brits are out of work because of immigration?

Probably not.

Now, Mrs May might be referring to a 2012 study by the Government’s Migration Advisory Committee, which did find some evidence of “displacement” in the labour market, but only in economic downturns and only from non-European immigration.

The MAC also asked people not to take its work as conclusive proof that immigration causes British job losses:

Our study has numerous qualifications and caveats. In particular, any link between immigration and employment of British-born people cannot be proved to be causal. Rather, it should be thought of as an association.

And of course, the MAC paper is merely one study of this issue. There are lots of others, some of which find no evidence of displacement.

There are so many studies that in 2014, the UK Government asked its officials to assess and analyse them. Some of those officials were from the Home Office, then run by Mrs May.
