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.
Dutch in Belgium
The last official census count in Brussels dates from 1947. At that time, the proportions were 24.24% Dutch-speaking and 70.61% French-speaking. Since then no official census have been carried out (these were abolished under Flemish political pressure because they were often performed unreliable and could not be an argument for further 'minorizing' Dutch). Since then, it has been necessary to rely on other sources to get an idea of the number of Dutch and French speakers in Brussels.
