20th century also has brought increased ethnic heterogenization to the British population, not only in ethnicity and race, but also in country of birth. In 2001, the White British population was registered to be 88.52% of the total population, but by 2011, this proportion of the population had dropped to 81.88%, with other ethnic groups either rising by 50% of their respective total population in 2001 or doubling entirely. Such rapid immigration growth boosted population growth in the United Kingdom. In 2011, the population sat at around 63 million people. Population The population of the UK in the last recorded census in 2011 was 63 million, of whom 31 million were male and 32 million female. The 2011 census recorded the population of England as 53.0 million, Scotland as 5.3 million, Wales as 3.1 million, and Northern Ireland as 1.8 million. At the last recorded population estimate, it was estimated that the UK population was at a total of 67,081,234 people. There are 13 urban areas that exceed 500,000 inhabitants: they are centred on London, Birmingham, Glasgow, Leeds and Bradford, Southampton and Portsmouth, Sheffield, Liverpool, Leicester, Manchester, Belfast, Bristol, Newcastle upon Tyne and Nottingham. According to the World Population Review, in 2019 there was: One birth every 39 seconds One death every 52 seconds A net gain of one person every minute One net migrant every 3 minutes Population by constituent country Population change over time The following table shows the total UK population estimated at census dates. Pre 1901 figures include the whole of Ireland, whereas from 1901 onwards only the population of Northern Ireland is included. Population density calculated on: Pre-1901: 243,820 km2 total land area for the United Kingdom plus 70,273 km2 land area of the Republic of Ireland. Post-1901: its current boundaries. Future projections The UK government first began publishing population projections for the country in the 1920's under the Government Actuary’s Department (GAD) which were mainly produced to be used for long-term financial estimates for pensions and other schemes of social insurance. However since the Second World War, population projections have taken an expanded role in all areas of influencing government policy. The GAD produced population projections every year from 1955 to 1979 and then switched it to every 2 years up to 1991. The Office of National Statistics took control of producing population projections for the country in 2006. The British Office for National
