The pro-Brexit campaign was built on a heavy anti-immigrant platform, and Britain’s EU referendum seems to be having the effect Leave voters wanted.

In the three months after the June 2016 referendum, net long-term migration fell by 19%, according to data released by the UK’s Office for National Statistics (ONS) today (Nov. 30). The number has continually fallen in the year since then.
