After Tax Income Gini coefficient

This map computes the GINI coefficient based on the 2010 after tax household income in each area. Overall, Canada's Gini coefficient was 0.39 in 2010. Compare this to the corresponding maps based on 2015 income data and based on 2005 income data. On a national or provincial level the GINI coefficient can be viewed as a measure of economic inequality. Prince Edward Island, Yukon and Northwest Territories were Canada's most equal provinces with a Gini coefficient of 0.35, British Columbia was Canada's least equal province at 0.40. When zooming into smaller regions, an increasing GINI coefficient can be interpreted as a measure of segregation. For example, the city of Vancouver has an overall Gini coefficient of 0.45, and when zooming in we see how in some areas the Gini index drops dramatically, for example to 0.39 in Southlands and the south-west corner of the West End, indicating economic segregation. Vancouver leads the major Canadian cities in economic inequality, Toronto follows with 0.44, Montreal at 0.43, Calgary at 0.40 and Edmonton at 0.39. For more information on the Gini coefficient see the excellent overview by Our World In Data. Definitions We compute the Gini using the after tax household income brackets. We make the simplifying assumption that the income in each bracket is uniformly distributed as the average income in that bracket. We grey out areas where household income information is not available, when we detect large statistical rounding in the data that might effect accuracy or when we detect that our assumptions on the income distribution lead to larger distortions.
