Apartment blocks of the Cité-Nouvelle

Onex is first mentioned in 1292 as Onay.[3] It became an independent municipality in 1851 when the municipality of Onex-Confignon split into the two municipalities of Onex and Confignon.[4]

Until the 1960s the municipality remained a relatively small agricultural village. This changed when, at the urging of the canton, it sold approximately 11 hectares (27 acres) to the Cité-Nouvelle Foundation to build public housing. The Foundation built a number of nine to fifteen story apartment blocks on the land to help relieve a housing shortfall in Geneva. The Cité-Nouvelle was one of the first high density housing blocks on the outskirts of Geneva. Between 1950 and 1970 the population increased from less than 1000 to over 13,0000. With the population growth, the village economy changed from primarily agricultural to a commuter and service economy. In 2000 about 90% of the population commuted to jobs outside the municipality and by 2005 about 90% of the jobs in the municipality were in the service sector.[3]
