This map, created by Phd student Ed Manley and James Cheshire, a lecturer at UCL’s Centre of Advanced Spatial Analysis, shows how linguistic groups are clustered in London.
The data is based on 3.3 million tweets sent over the summer and was gathered via an open source website language detector.
Unsurprisingly, 92.5% of the tweets were sent in English, but in total there were 66 languages represented – including Haitian Creole, Basque, and Swahili.
Some of the more prominent languages include Turkish (blue), which were mainly sent in North London, while Arabic (green) featured prominently around Edgware Road and the West End. The pockets of pink are Russian tweets, and can be found dotted all over the city.
Most surprisingly of all though is French – the red areas. They appear to be in very high-density pockets around the city centre, but not so much in South Kensington – where the French population tends to end up and where the embassy, Institut Francais, and French High School are all located.
