Demographics of Belgium
Belgium's three official languages are Dutch, spoken by 59% of the population, French, spoken by 40%, and German, spoken by less than 1%. The vast majority of Belgium's population, 99%, is literate as defined by the Belgian government, i.e. capable of reading and writing in an official language by the time a citizen has reached the age of 15.
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.
