The United Kingdom’s population is likely to grow to 71.0 million by mid-2034, below a previous projection of 72.2 million due to lower immigration assumptions, the country’s statistics office said ​on Tuesday.

Net immigration looks set to add 2.2 million people to the UK’s population of ​69.3 million between mid-2024 and mid-2034, while there would be a drag of 450,000 ⁠from deaths exceeding births, the Office for National Statistics said.

The ONS also trimmed its assumption for fertility to 1.42 children per woman from 1.45 in its last projections made two years ago.

There was a more substantial cut to the ONS’ assumption for future rates of ​net immigration to 230,000 a ​year from 340,000 in ⁠the 2024 report.

After net immigration approached 1 million in the 12 months to June 2023, rules were tightened and it fell to 204,000 in ⁠the 12 ​months to June 2025.
