The population of the UK at mid-year 2020 was estimated to be 67.1 million, an increase of about 284,000 (0.4%) since mid-year 2019.
In the year to mid-2020, there were 669,000 deaths; this is the most in a mid-year reference period since 1986, and 13% higher than in the year to mid-2019, reflecting the impact of wave one of the coronavirus (COVID-19) pandemic.
The number of births in mid-2020 was 701,000, the lowest number of births since 2003 and a continuation of the trend in fewer births seen over recent years.
These estimates are based on the Labour Force Survey, which has used a new weighting methodology to reflect the change in survey operations during the coronavirus (COVID-19) pandemic; Data below UK, EU and non-EU level should be treated with caution and not be compared with previous years.
We will be updating our estimates to provide the best picture of the population as more information becomes available, particularly the results from the 2021 Census, which will give further insight when published next year.
In the year ending June 2021, the non-UK-born population was an estimated 9.6 million and the non-British population was an estimated 6.0 million; both the non-UK-born population and non-British population have remained broadly stable since 2019.
Different migration-related data sources at local authority level including migration flows, non-UK-born and non-British populations, National Insurance number registrations, GP registrations, and births to non-UK-born mothers.
