In Berlin, numerous cafés, restaurants, and also extracurricular educational venues, such as music classes and cultural associations, exhibit multilingualism and are an integrative part of the city. The city is also strongly characterized by child multilingualism: More than half of preschool-age children are multilingual. Different languages are often heard on the streets of different districts, for example, Turkish in Neukölln or English in Wilmersdorf. However, there is no reliable data on the distribution of different languages and their speakers in Berlin.

The project "Language Map of Berlin" aims to close this gap. It is planned to first create a Language Map in one multilingual district, Pankow. In this district the multilingual parents have founded the association lingua Pankow, which has agreed to support the recording of the language distribution. Thus, the foundation for the creation of the Language Map of Berlin will be laid and the basis for the project with the Humboldt University of Berlin, the BBAW and the Endangered Languages Documentation Programme (ELDP) will be developed.
