I watched a report on the BBC about statistics for England and Wales regarding the numbers of people born outside those countries, but resident in them as of late 2021.
(Scotland was not included as it had not participated in the survey.)

I looked up some of the details available.

People born in India top the list, with a total of 920,000 born in India, but living in England or Wales.

760,000 people who were born in Poland also have a British passport, along with 539,000 people born in Romania.

EU nationals account for 36.4% of those born abroad, but living in England or Wales.

Between 2011 and 2021, the population of England and Wales rose by over 3,000,000 as a result of foreign-born migrants, according to the Office of National Statistics.

Other nationalities in the top five include Pakistan, and Ireland. Total numbers of foreign-born residents now exceed 10,000,000, almost 14% of the population.

Over 35% of all foreign-born nationals living in England and Wales live in Greater London

I find all of this fascinating. As a former Londoner, I can confirm the last figures. London is incredibly diverse, and the different cultures have added to the overall enjoyment of living in that city.

However, where I live now, in Beetley in rural Norfolk, I could count foreign-born nationals on both hands and have fingers to spare.
