Demographics of Belgium
Belgium's three official languages are Dutch, spoken by 59% of the population, French, spoken by 40%, and German, spoken by less than 1%. The vast majority of Belgium's population, 99%, is literate as defined by the Belgian government, i.e. capable of reading and writing in an official language by the time a citizen has reached the age of 15.
Brussels-Halle-Vilvoorde
In 1921 Belgium was divided into two monolingual entities (French-speaking Wallonia and Dutch-speaking Flanders). Both languages could be used in Brussels (16 municipalities at that time). A special status was established wherever a large minority used the other language along the linguistic border.
