Belgium
Belgium has three official languages: Dutch, French and German. A number of non-official minority languages are spoken as well.
As no census exists, there are no official statistical data regarding the distribution or usage of Belgium's three official languages or their dialects. However, various criteria, including the language(s) of parents, of education, or the second-language status of foreign born, may provide suggested figures. An estimated 60% of the Belgian population are native speakers of Dutch (often referred to as Flemish), and 40% of the population speaks French natively. French-speaking Belgians are often referred to as Walloons, although the French speakers in Brussels are not Walloons.
Football in Belgium
A Belgian club's name usually includes the name of the town where the club plays as well as a prefix and/or suffix. Since Belgians speak three languages, French and Dutch being the main ones and German being the third official language, Belgian teams may use either language as the basis for their names. For historical reasons, many Flemish clubs changed their names from French to Dutch between the beginning of the 20th century and the late 1960s. Additionally, many clubs have experienced frequent name changes. Reasons for these include a language change, a merger, an anniversary, etc. Because of the numerous mergers between Belgian clubs, team names sometimes combine several town names (such as K. Beringen-Heusden-Zolder or Sporting West Ingelmunster-Harelbeke) which reflect mergers. In recent history, clubs representing immigrant communities have come into existence and sometimes use names that are in neither of Belgium's official languages (the now defunct clubs Türkgucun Ozburun and Türkiyemspor Zaventem, or the still-existing Agrupación Oviedo-Asturiana, existing only in a league outside the Belgian FA now, from Brussels, being examples).
