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.
Municipalities of Belgium
Article 4 of the constitution states that each municipality must belong to only one of the four official language areas that were established in 1962–63. In the three officially unilingual language areas, a couple of dozen municipalities in the vicinity of another language area must provide limited facilities for speakers of that other language. As only a law carried by special majorities can change the language status of any municipality, these arrangements have prevented some small municipalities with facilities to be merged in the 1970s, and thus the most minute Belgian municipalities are still found in this group, notably Herstappe with only 84 inhabitants (in 2006).
