Yvelines (French pronunciation:  [ivlin] ) is a department in the region of Île-de-France, France. Located west of Hauts-de-Seine, it had a population of 1,431,808 as of 2016. Its main cities are Versailles, Saint-Germain-en-Laye, Mantes-la-Jolie and Rambouillet.

In the administrative divisions of France, the department is one of the three levels of government below the national level, between the administrative regions and the commune. Ninety-six departments are in metropolitan France, and five are overseas departments, which are also classified as regions. Departments are further subdivided into 334 arrondissements, themselves divided into cantons; the last two have no autonomy, and are used for the organisation of police, fire departments, and sometimes, elections.

Regions of France France top-level territorial subdivision

France is divided into 18 administrative regions, which are traditionally divided between 13 metropolitan regions, located on the European continent, and 5 overseas regions, located outside the European continent. The 13 metropolitan regions are each further subdivided into 2 to 13 departments, while the overseas regions consist of only one department each and hence are also referred to as "overseas departments". The current legal concept of region was adopted in 1982, and in 2016 what had been 27 regions was reduced to 18. The overseas regions should not be confused with the overseas collectivities, which have a semi-autonomous status.

Île-de-France, often called the région parisienne due to containing the city of Paris, is north-central and the most populous of the 18 regions of France. It covers 12,012 square kilometres, or two percent of the national territory, and has official estimated population of 12,213,364 as of January 1, 2019, or 18.2% of the population of France. The region accounts for nearly 30 percent of the French Gross Domestic Product (GDP).



Yvelines was created from the western part of the former department of Seine-et-Oise on 1 January 1968 in accordance with a law passed on 10 January 1964 and a décret d'application (a decree specifying how a law should be enforced) from 26 February 1965. It inherited Seine-et-Oise's official number of 78.

Seine-et-Oise former French department (1790-1968)

Seine-et-Oise was a département of France encompassing the western, northern, and southern parts of the metropolitan area of Paris. Its préfecture (capital) was Versailles and its official number was 78. Seine-et-Oise was abolished in 1968 as part of the reorganization of the départements of the Paris metropolitan area.

It gained the communes of Châteaufort and Toussus-le-Noble from the adjacent department of Essonne in 1969.

The commune is a level of administrative division in the French Republic. French communes are analogous to civil townships and incorporated municipalities in the United States and Canada, Gemeinden in Germany, comuni in Italy or ayuntamiento in Spain. The United Kingdom has no exact equivalent, as communes resemble districts in urban areas, but are closer to parishes in rural areas where districts are much larger. Communes are based on historical geographic communities or villages and are vested with significant powers to manage the populations and land of the geographic area covered. The communes are the fourth-level administrative divisions of France.

Since then the château has continued to welcome the French Parliament when it is called upon to sit in a congressional sitting (with both houses sitting together) in order to enact constitutional changes or to listen to a formal declaration by the president.

1This group is made up largely of former French settlers, such as pieds-noirs in Northwest Africa, followed by former colonial citizens who had French citizenship at birth (such as was often the case for the native elite in French colonies), and to a lesser extent foreign-born children of French expatriates. Note that a foreign country is understood as a country not part of France in 1999, so a person born for example in 1950 in Algeria, when Algeria was an integral part of France, is nonetheless listed as a person born in a foreign country in French statistics.
2An immigrant is a person born in a foreign country not having French citizenship at birth. Note that an immigrant may have acquired French citizenship since moving to France, but is still considered an immigrant in French statistics. On the other hand, persons born in France with foreign citizenship (the children of immigrants) are not listed as immigrants.
