Languages of Belgium
Before the federal structure and the language legislation gradually introduced in the 20th century, French was generally the only language used by public authorities. For example, the Dutch version of the Constitution has enjoyed equal status to the original French one only since 1967, and the German version only since 1991.
Of the inhabitants of Belgium, roughly 59% belong to the Flemish Community, 40% to the French Community and 1% to the German-speaking Community, though these figures relating to official Belgian languages include unknown numbers of immigrants and their children speaking a foreign language as primary language, and of Belgian regional migrants which may be assumed to largely balance one another for natively French and Dutch speakers. Though the standard form of Dutch used in Belgium is almost identical to that spoken in the Netherlands and the different dialects spread across the border, it is often colloquially called "Flemish".
Chamber of Representatives (Belgium)
Article 62 of the Belgian Constitution fixes the number of seats in the Chamber of Representatives at 150. There are 11 electoral districts, which correspond with the ten Provinces (five Dutch- and five French-speaking) and the Brussels-Capital Region. Prior to the sixth Belgian state reform, the province of Flemish Brabant was divided into two electoral districts: one for Leuven and the other, named Brussels-Halle-Vilvoorde (BHV), which encompassed both the 19 bilingual municipalities from the Brussels-Capital Region and the 35 Dutch-speaking municipalities of Halle-Vilvoorde in Flemish Brabant, including seven municipalities with linguistic facilities for French-speaking inhabitants.
