The 1932 law was implemented only once, as the invasion of Belgium by Nazi Germany in 1940 prevented the organization of the decennial census, which was organized in 1947 and applied only on 2 July 1954, when an ad hoc law modifying the law of 28 June 1932 on the use of languages for administrative matters transferred three previously unilingual Flemish municipalities with language facilities to the French-speaking minority (Evere, Ganshoren, and Sint-Agatha-Berchem) to the bilingual region of Brussels, thus and introduced language facilities for the French-speaking minority in four previously unilingual Flemish municipalities (Drogenbos, Kraainem, Wemmel, and Linkebeek).
