Seine-et-Oise () is a former department of France, which encompassed the western, northern and southern parts of the metropolitan area of Paris. Its prefecture was Versailles and its administrative number was 78. Seine-et-Oise was disbanded in 1968 as part of the reorganisation of the departments of the Paris metropolitan area. The newly created Yvelines department inherited the 78 number.
General characteristics
Seine-et-Oise was created on 4 March 1790 during the French Revolution.
Population
At the 1999 French census, the population of the former department of Seine-et-Oise was 4,554,426 inhabitants, its highest figure ever, as people relocated more and more from the center to the distant suburbs of the metropolitan area of Paris. Of the new departments created in 1968 from Seine-et-Oise, Yvelines was the most populous in 1999 with 1,354,304 residents. Seine-Saint-Denis and Hauts-de-Seine are more populous than Yvelines, but only a small part of their territory is made up of the former Seine-et-Oise.
