Provinces of Belgium
The country of Belgium is divided into three regions. Two of these regions, the Flemish Region or Flanders, and Walloon Region, or Wallonia, are each subdivided into five provinces. The third region, the Brussels-Capital Region, is not divided into provinces, as it was originally only a small part of a province itself.
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).
