The population of the Anglia region grew by more than 70,000 people in the year ahead of the EU Referendum in 2016.
In the latest population estimates released by the Office of National Statistics (ONS), the number of people in Anglia region had reached 7.3 million in June 2016. That was up 73,144 on the previous year.
In the decade since 2006, the population has grown by 10% with an additional 649,415 people living in the region.
The ONS says population of the UK at 30 June 2016 is estimated to be 65,648,000 people, up by 0.8% or 538,000 people.
In the six counties that make up the East of England - Bedfordshire, Cambridgeshire, Essex, Hertfordshire, Norfolk and Suffolk - the population was 6,130,542, up by 54,091 or 0.9% on the previous year.
One third of the population increase in the East is down to natural demographics - more people are being born in the region than dying. There were nearly 18,000 more births than deaths between 2015 and 2016.
A large proportion of the rise in population, 38%, is down to migration from abroad while 28% of it is down to people moving to the region from elsewhere in the UK.

Welwyn Hatfield’s population grew by 2,980 to 121,996 in June 2016 but was split between migration from abroad (43%) and migration from elsewhere in the UK (41%).
