These boroughs are the result of several waves of amalgamation and reorganization of the political boundaries of Quebec City.
The six boroughs are further divided into 36 quartiers ("neighbourhoods"), which are as of 2005[update] numbered instead of named.
From January 1, 2002 to October 31, 2009, the city had eight boroughs: La Cité, Les Rivières, Sainte-Foy–Sillery, Charlesbourg, Beauport, Limoilou, La Haute-Saint-Charles and Laurentien.
The boroughs of La Cité and Limoilou were merged on November 1, while the borough of Laurentien was dissolved and divided between Sainte-Foy–Sillery–Cap-Rouge and La Haute-Saint-Charles.
Former cities are still commonly referred to by their former names even though their administrative structures no longer exist.
