Chart 2, Time series of Gini coefficients for the US and Australia between 1995 and 2014. Gini coefficients are calculated using both market income and disposable income. The US and Australia have fairly similar Gini coefficients when calculated using market incomes. However, after taking into account each country's tax and transfer system, Gini coefficients calculated using disposable incomes are noticeably lower in Australia than in the US. For disposable income, the US Gini coefficient grows from 0.36 to 0.39, and the Australia Gini coefficient from 0.31 to 0.34.The gap between the Australian and US disposable income Gini coefficients has been broadly constant over time.
