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.
Multilingualism
In Europe, as the domestic market is generally quite restricted, international trade is a norm. But there is no predominant language in Europe (with German spoken in Germany, Austria, Switzerland, Luxembourg, and Belgium; French in France, Belgium, Luxembourg, and Switzerland; and English in the United Kingdom, Ireland, and Malta). Most of the time, English is used as a communication language, but in multilingual countries such as Belgium (Dutch, French and German), Switzerland (German, French, Italian and Romanche), Luxembourg (Luxembourgish, French and German) or Spain (Spanish, Catalan, Basque and Galician), it is common to see employees mastering two or even three of those languages. Some languages such as Danish, Swedish and Norwegian or Croatian, Slovenian, Serbian and Bosnian are so close to each other that it is generally more common for meeting to use their mother tongue rather than English.
