Read Language in England and Wales - Office for National Statistics (ons.gov.uk)

Using data from the 2011 Census, we take a closer look at language within England and Wales. Those who reported English (or Welsh in Wales) as their main language accounted for 92.3% of the population, except in London where proportion was much lower. Those who reported another main language accounted for 7.7% of the population, with Polish topping the list of "other" main languages. London and the West Midlands saw the highest percentage of people who could not speak English "well" or "at all".
