Belgian literature
Because Belgium is a multilingual country, Belgian literature is divided into two main linguistic branches following the two most prominently spoken languages in the country - Dutch and French. German is the third language in Belgium and is spoken by a small community of about 70,000 German-speakers of the German-speaking Community of Belgium bordering on Germany.
Demographics of Belgium
The exact number of French-speakers in Brussels is hard to determine, but it is estimated that 80% of the people living in Brussels use French and 20% use Dutch in their households, as the sole language or secondary language, while Arabic is also largely spoken. See the Brussels article for more details.
