Languages of Belgium
In addition to the three official languages, others are spoken in Belgium, like in Wallonia, where French became dominant only relatively recently. Sometimes seen as dialects, the varieties related to French have been recognized by the French Community as separate languages ("", ‘regional native languages’) since 1990, without, however, taking any further significant measures to support those varieties.
Demographics of Belgium
The exact number of French-speakers in Brussels is hard to determine, but it is estimated that 80% of the people living in Brussels use French and 20% use Dutch in their households, as the sole language or secondary language, while Arabic is also largely spoken. See the Brussels article for more details.
