Champigny-sur-Marne was originally called simply Champigny. The name Champigny ultimately comes from Medieval LatinCampaniacum, meaning "estate of Campanius", a Gallo-Roman landowner.
In 1897 the name of the commune officially became Champigny-sur-Marne (meaning "Champigny upon Marne"), in order to distinguish it from other communes of France also called Champigny.
Demographics
Immigration
Place of birth of residents of Champigny-sur-Marne in 1999
¹This group is made up largely of pieds-noirs from 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 as of 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.
² An 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.
Champigny-sur-Marne is also served by Champigny station on Paris RER line A. This station, although administratively located on the territory of the neighboring commune of Saint-Maur-des-Fossés, lies immediately across the Marne River from the town center of Champigny-sur-Marne and is thus used by people in Champigny.
