At the 2011 Census, Balwyn North had a population of 20,317.GeographyThe north-west part of the suburb is known as Bellevue and the south-east part is known as Greythorn.HistoryBalwyn North was one of the first Melbourne suburbs to be developed according to the pattern of postwar suburbia, with expansive, quiet residential areas designed as family homes and relatively few business districts. The original route of Bulleen Road began at the present-day corner of Kilby Road and Burke Road, but by the 1900s, its route had changed to its present-day alignment. This was a result of Elgar's Special Survey, which dragged the alignment of Burke Road further west, resulting in the surrounding road network being forced to adjust.A Balwyn North Post Office opened on 1 April 1937. This was renamed Burke Road in 1941, when a new Balwyn North office opened at its current location. The Greythorn Post Office opened in 1951.EducationLocated in Balwyn North are several primary schools, such as Greythorn, Balwyn North and Bellevue. Balwyn High School is located on Buchanan Avenue, and is so highly sought after, particularly by Asian families, that property prices within its student catchment area sell for hundreds of thousands of dollars more than nearby properties not located in the area.
