There are also many immigrant languages spoken in the British Isles, mainly within inner city areas; these languages are mainly from South Asia and Eastern Europe.

(According to 2011 census data, 864,000 people in England and Wales reported speaking little or no English.) An estimated 700,000 people speak Welsh in the UK, an official language in Wales and the only de jure official language in any part of the UK.
