evidence: Over the 10 years between 2011 and 2021, the population of England increased by 6.5% to an estimated 56,536,000, the highest rate of the four countries of the UK; the estimated population of Northern Ireland increased by 5.0% to 1,905,000, Scotland by 3.4% to 5,480,000, and Wales by 1.4% to an estimated 3,105,000. [...] Overall, England had the highest population density of the four countries of the UK at mid-2021. However, this includes a wide variation within England, where the population density in London was 5,596 people per square kilometre (km) and the South West was 240 people per square km. [...] We plan to publish population estimates for England and Wales in Summer 2023. The Northern Ireland Statistics and Research Agency (NISRA) also plan to release mid-2022 population estimates in Summer 2023. Details of its release plans can be found in its Population Statistics Work Plan.
