This map of Toronto's income inequality compares changes in average individual income over the past 40 years, based on research by David Hulchanski and Richard Maaranen with the Neighbourhood Change Research Partnership at the University of Toronto.

Individual income for persons 15 and over, from all sources, before-tax. Change is in terms of percentage points. The 2010 average individual income of the census tract is divided by the metropolitan area average for that year and the same is done for 1970. The difference (2010 minus 1970) is multiplied by 100 to produce the percentage point change for each census tract.
