Geographical distribution of French speakers in the context of "Long and short scale"

Wallonia (/wɒˈloʊniə/ wol-OH-nee-ə; French: Wallonie [walɔni] ; German: Wallonien [vaˈloːni̯ən] or Wallonie [valoˈniː] ), officially the Walloon Region (French: Région wallonne [ʁeʒjɔ̃ walɔn]; German: Wallonische Region [vaˈloːnɪʃə ʁeˈɡi̯oːn]), is one of the three regions of Belgium—along with Flanders and Brussels. Covering the southern portion of the country, Wallonia is primarily French-speaking. It accounts for 55% of Belgium's territory, but only 31% of its population. The Walloon Region and the French Community of Belgium, which is the political entity responsible for matters related mainly to culture and education, are independent concepts, because the French Community of Belgium encompasses both Wallonia and the bilingual Brussels-Capital Region but not the German-speaking Community of Belgium, which administers nine municipalities in Eastern Wallonia.

During the Industrial Revolution, Wallonia was second only to the United Kingdom in industrialization, capitalizing on its extensive deposits of coal and iron. This brought the region wealth, and from the beginning of the 19th to the middle of the 20th century, Wallonia was the more prosperous half of Belgium. Since World War II, the importance of heavy industry has greatly diminished, and the Flemish Region has exceeded Wallonia in wealth as Wallonia has declined economically. Wallonia now suffers from high unemployment and has a significantly lower GDP per capita than Flanders. The economic inequalities and linguistic divide between the two are major sources of political conflicts in Belgium and a major factor in Flemish separatism.

A gendarmerie (/ʒɒnˈdɑːrməri, ʒɒ̃-/) is a military or paramilitary force with law enforcement duties among the civilian population. The term gendarme (English: /ˈʒɒndɑːrm/) is derived from the medieval French expression gens d'armes, which translates to 'men-at-arms' (lit. 'people of arms'). In France and some Francophone nations, the gendarmerie is a branch of the armed forces that is responsible for internal security in parts of the territory (primarily in rural areas and small towns in the case of France), with additional duties as military police for the armed forces. It was introduced to several other Western European countries during the Napoleonic conquests. In the mid-twentieth century, a number of former French mandates and colonial possessions (such as Lebanon, Syria, the Ivory Coast and the Republic of the Congo) adopted a gendarmerie after independence.

Similar forces exist in most European countries. The European Gendarmerie Force is a structure, aligned with the European Union, that facilitates joint operations. A similar concept to gendarmerie exists in Russia in the form of internal troops, which are present in many CIS states.

The long and short scales are two powers of ten number naming systems that are consistent with each other for smaller numbers, but are contradictory for larger numbers. Other numbering systems, particularly in East Asia and South Asia, have large number naming that differs from both the long and the short scales. Such numbering systems include the Indian numbering system and Chinese, Japanese, and Korean numerals. Much of the remainder of the world has adopted either the short or long scale. Countries using the long scale include most countries in continental Europe and most that are French-speaking, German-speaking and Spanish-speaking. Use of the short scale is found in most English-speaking and Arabic-speaking countries, most Eurasian post-communist countries, and Brazil.

For powers of ten less than 9 (one, ten, hundred, thousand, and million), the short and long scales are identical; but, for larger powers of ten, the two systems differ in confusing ways. For identical names, the long scale grows by multiples of one million (10), whereas the short scale grows by multiples of one thousand (10). For example, the short scale billion is one thousand million (10), whereas in the long scale, billion is one million million (10), making the word 'billion' a false friend between long- and short-scale languages. The long scale system includes additional names for interleaved values, typically replacing the word-ending '-ion' with '-iard'.

Varieties of the French language are spoken in France and around the world. The Francophones of France generally use Metropolitan French (spoken in Paris and considered standard) although some also use regional dialects or varieties such as Meridional French. In Europe outside France there are Belgian French, Swiss French, and in Italy Aostan French. In Canada, French is an official language along with English; the two main dialects of French in Canada are Canadian French and Acadian French. Standard French (e.g. used by Anglophones speaking French or by Francophones in Canada using a different dialect) is also commonly grouped as Canadian French. In Lebanon, French was an official language until 1941 and the main dialect spoken there is Lebanese French or Levantine French. Levantine French was also spoken by Sephardic Jews in Thessaloniki, Istanbul and Smyrna, by Armenians and Greek bourgeois in the urban centres of Asia Minor, by Syrian Catholics and Melkites in Aleppo and Beirut.

Note that the discussion here refers to varieties of the French language, not to the Romance sister languages (sometimes considered dialects) of French spoken in France (e.g. Picard, Limousin, Gascon, etc.; for these languages see: Langues d'oïl, Francoprovençal, Occitan and languages of France). See also French-based creole languages, which are also considered separate languages.
