We look at the main language of UK residents, and their ability to speak English if English isn't their main language. We also look at how the self-reported ability to speak English related to general health. English (or Welsh in Wales) was the main language for 92% of UK residents. Of the remaining 8% who had a different main language, the majority could speak English "well" or "very well". People who couldn’t speak English "well" or "at all" had a lower proportion of "good" general health than those with English as their main language.
