London has become one of the most ethnically diverse cities in the world, with more than 300 languages spoken in Greater London. Request access to London's diverse population. London was the most ethnically and religiously diverse region in England and Wales, where the most important ethnic groups were white Britons (43.4%), other whites (14.6%) and black Africans (7.9%); people with a religion other than Christian represented more than 25% of the population of London, compared to an estimated 10.6% of the total population. At the outbreak of World War II, 8,615,245 people were living in London, although by then it had just lost its status as the largest city in the world in favor of New York.
In addition, there was a higher percentage of young people among Muslims compared to the total population of England and Wales; an estimated 9.7% of people aged 0 to 19 were Muslims, compared to 5.7% of the total population. It is the third largest city in Europe, behind Istanbul (14.8 million) and Moscow (10.3 million), and the 27th most populated metropolitan area in the world, slightly larger than Lima, Peru. Nearly 40% of all London residents were born abroad, making it the second highest immigrant population in the world. People living in London and the South East constituted 30.4% of the total population of England and Wales.
Allerdale, in the northwest, was the least ethnically diverse of all local authorities, with whites representing 98.5% of the population; they represented 98.2% of the population in both Torridge and Ryedale. Although not a country in itself, London is the largest city in the United Kingdom and represents 13% of the total population of the United Kingdom. Of the 10 local authorities where whites constituted the largest percentage of the population, 3 were in the North West, 2 in Yorkshire and the Humber and 2 in the South West. While this is a possible answer in the Annual Population Survey (APS), due to a difference in the way data is collected, it is only available if the respondent spontaneously refuses, which means that it is present for a much smaller proportion of respondents (around 0.25% at the level of England and Wales).
