Migration has slowed since the referendum, but that hasn’t stopped the population hitting 66 million

An almost 400,000 increase in migration to the UK pushed the population up to a record breaking 66 million last year.

But growth has slowed down significantly since the EU referendum – with the 0.6 per cent increase the lowest since 2004.

The expansion in the 12 months to mid-2017 is roughly equivalent to adding a city the size of Coventry.

Some 41 per cent of the increase was down to the birth rate exceeding the death rate, the Office for National Statistics said.

The other 59 per cent was due to net international migration.


London saw the sharpest slowdown, with the increase slumping from 1.19 per cent in the previous year to 0.63 per cent.

England as a whole saw numbers go up by 0.64 per cent or 351,400, while the level in Scotland and Wales were much lower at 0.37 per cent and 0.39 per cent respectively.

The figures also set out the bulge in the age of the population as the Baby Boomer generation move into their later years.

Nearly 12million residents were aged 65 or over – 18.2 per cent of total.
