Although neighbouringPontoise is the officialpréfecture (capital) of theVal-d'Oisedépartement, thepréfecture building and administration, as well as the department council (conseil général), are located inside the commune of Cergy.

When Cergy was selected to become the center of a "new town", it was only a village. The commune had only 2,895 inhabitants in 1968. It then started to develop very quickly, exceeding 10,000 inhabitants in the mid-1970s and then 20,000 in the early-1980s. It is in this decade that its growth was most spectacular, since the city exceeded 48,000 inhabitants in 1990. The increase continued since, but at a notably slower pace, to reach 54,500 at 2004 estimates. However, in December 2001, the commune lost a portion of its territory (net 0.03 km2 (0.012 sq mi) with a 1999 population of 62 persons) to the adjacent commune ofCourdimanche.[5] The official census figures have thus been revised downward from the 1999 official 54,781 to 54,719, and the land area from 11.68 km2 (4.51 sq mi) to 11.65 km2.
1 This group is made up largely of former French settlers, such aspieds-noirs inNorthwest 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), as well as to a lesser extent foreign-born children of French expatriates. 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.
2 An immigrant is a person born in a foreign country not having French citizenship at birth. 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.
