Communities, regions, and language areas of Belgium

Belgium is a federal state comprising three communities and three regions that are based on four language areas. For each of these subdivision types, the subdivisions together make up the entire country; in other words, the types overlap.

The language areas were established by the Second Gilson Act, which entered into force on 2 August 1963. The division into language areas was included in the Belgian Constitution in 1970.^[1] Through constitutional reforms in the 1970s and 1980s, regionalisation of the unitary state led to a three-tiered federation: federal, regional, and community governments were created, a compromise designed to minimize linguistic, cultural, social, and economic tensions.^[2]
