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.
