Gini coefficients
This map shows Gini coefficients based on adjusted household income, and given relative to the total income, market income or after-tax income. Adjusted household income is the income of the household divided by the square root of the number of people in the household. This (somewhat crudely) accounts for the fact that one requires a higher household income for larger households, but there are synergies because of shared services so a household twice as large does not require twice as much income in order to have a comparable lifestyle. This is the first time StatCan provided this as a derived statistic in the standard release profile data, in previous censuses we have estimated Gini coefficients from the income distribution, but this method cannot take into account adjusted household income which is a more useful concept. Without adjusting for household size the Gini coefficient can become inflated because e.g. of mixing of one-person and multiple person households. Use the buttons up top to flip back and forth between the different income concepts. Changing between total and after-tax income shows how taxes work to reduce inequality as measured by the Gini coefficient. Compare this to the map of the ratio of the 90th to the 10th percentile of the adjusted after-tax household income, another useful income inequality measure.
