These figures relating to official Belgian languages include unknown numbers of immigrants and their children, who may speak a foreign language as primary language, and of Belgian regional migrants, who likely largely balance one another for native French and Dutch speakers. A large French-speaking population lives around Brussels, in Flanders, and by geography are considered part of the Flemish Community. Though the standard form of Dutch used in Belgium is almost identical to that spoken in the Netherlands, and the different dialects across the border, it is often colloquially called "Flemish".
