Belgium
Belgium has three official languages: Dutch, French and German. A number of non-official minority languages are spoken as well.
As no census exists, there are no official statistical data regarding the distribution or usage of Belgium's three official languages or their dialects. However, various criteria, including the language(s) of parents, of education, or the second-language status of foreign born, may provide suggested figures. An estimated 60% of the Belgian population are native speakers of Dutch (often referred to as Flemish), and 40% of the population speaks French natively. French-speaking Belgians are often referred to as Walloons, although the French speakers in Brussels are not Walloons.
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).
