evidence: EU immigration to the UK An estimated 202,000 citizens from other EU countries immigrated to the UK in the year to September 2018, and about 145,000 emigrated abroad. So EU ‘net migration’ was around 57,000—roughly the lowest level recorded since 2009. [...] Since the EU referendum in late June 2016, the estimated number of EU nationals immigrating to the UK fell from 284,000 the year before the vote to 226,000 in the year after. That’s now down to 202,000.
