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.
Dutch in Belgium
Based on differences sources, the number of Dutch speakers in the Brussels-Capital Region can currently be estimated at 5 to 8 percent.
In 2011, on average 7% of the Brussels customers of the largest Brussels telecom operator Belgacom received their invoices in Dutch, 91% in French and 2% in another language. 
The number of Dutch-language invoices turned out to be considerably higher in the northeast of the region than in the southwest (8 to 12% versus 3 to 5%).
Dutch is the official language in Flanders, but there are a number of Flemish municipalities in the Brussels Periphery with a French-speaking majority, which are officially Dutch-speaking with French-language facilities.
