Brussels, the capital of Belgium is not just home to the European Parliament, but also one of the world’s most multicultural cities. Census data is commonly utilised to create maps that show the distribution of ethnic communities. Yet as large volumes of geotagged data from Twitter become increasingly available, new opportunities arise to study the spatial behaviour of people.
Visualising geotagged tweets from 2013, we show the geographic distribution of language use with 7 different maps that emphasise particular data patterns. French, Dutch and English, the common tongue of Brussels, have been removed from this study to emphasise ethnic languages. Notably, the dispersion of such languages are observed to co-locate with communal institutions, landmarks and even certain municipals. Some noteworthy examples have been highlighted on this map.
