Demographics

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 with a 1999 population of 62 persons) to the adjacent commune of
