Net migration to UK decreased by 106,000 after Brexit vote
Net long-term migration to the UK fell by more than 100,000 in the year after the EU referendum, official figures show.
The measure - the difference between the numbers arriving and leaving the country for at least a year - was an estimated 230,000 in the 12 months to the end of June 2017.
This was a fall of 106,000 compared with the record level of 336,000 in the previous year.
The Office for National Statistics said over three-quarters of the decrease was accounted for by EU citizens.
EU net migration fell by 82,000 to 107,000, which was described as a "statistically significant" drop.
Statisticians said the figures indicate net migration has returned to levels seen in 2014 following a peak in the middle of last year.
Nicola White, head of migration statistics at the ONS, said: "Overall more people are still coming to live in the UK than are leaving and therefore net migration is adding to the UK population.
"The first full year of data since the EU referendum vote in 2016 shows a decrease in the number of people coming to live in the UK and an increase in the number leaving, resulting in a fall in net migration of 106,000.
"Over three-quarters of the fall in net migration was accounted for by EU citizens.
"The decline follows historically high levels of immigration and it is too early to say whether this represents a long-term trend.
"The number of people immigrating for a definite job has remained stable but there has been a 43% decrease in the number of people immigrating to look for work over the last year, especially for EU citizens.
"These changes suggest that Brexit is likely to be a factor in people's decision to move to or from the UK - but decisions to migrate are complex and other factors are also going to be influencing the figures."
