Level of income inequality in OECD countries
These charts compare overall income inequality in OECD countries, using the Gini coefficient, for which a higher score represents greater inequality. 2019-20: The chart shows that income inequality in Australia in 2021 or latest available date is close to the average level for wealthy nations, based on OECD data. 2017-18: The chart shows that income inequality in Australia in 2018 - the latest date for which comparative data is available - was close to the average level for wealthy nations. 2015-16: It shows that income inequality in Australia in 2015 – the latest date for which comparative data is available – was higher than the OECD average. Australia sits between other English-speaking countries, above Canada but below the United States and the United Kingdom; and alongside some countries with lower income levels, like Greece and Portugal. Most European countries had much lower income inequality than Australia.
Trends in average weekly disposable income since 1999-00
This shows how average household incomes grew in ‘real terms’ (after inflation) for the lowest, middle and highest 20% income groups in Australia, as well as the highest 5%. It shows that income growth was very uneven during the boom from 1999-00 to 2007-08. The average income of the lowest 20% grew by 5.6% per year in real terms, compared with 5.9% for the middle 20%, 7.2% for the highest 20%, and 10.3% for the highest 5%. After the Global Financial Crisis, from 2007-08 to 2015-16, household incomes grew much more slowly and less unequally. The average household incomes of the lowest 20% grew by 2.5% per year (aided by a large pension increase in 2009), compared with 0.3% for the middle 20%, 0.8% for the highest 20%, and a decline of 0.6% for the highest 5% (likely due to falls in returns from investments.
Average income tax paid by households
This shows the average (not marginal) tax rates paid by households (not individuals) in different income groups. Personal income taxes are progressive, so average tax rates increase with income. Households in the lowest 20% pay only 4% of their overall income in income taxes on average (including the Medicare Levy) compared with 15% for the middle 20% and 26% for the highest 20%. However, the progressive impact of income taxes is largely offset by the regressive impact of other taxes such as the Goods and Services Tax and Stamp Duties. Find out more.
Comparison of household disposable incomes
This table compares the minimum and average household incomes of the lowest 40% income group, the highest 5% and the highest 1%. In 2015-16, the average household income of the highest 1% was $11,682 per week, over ten times the average disposable income of the lowest 40% , which was $1,022 per week. Their incomes were almost twice that of the highest 5% and almost six times the overall average household disposable income ($2,033). The incomes of the highest 1% of households also increased more rapidly. Between 1999-00 and 2015-16, their average incomes rose 15% faster than the incomes of households in the highest 5%; and 42% faster than the lowest 40%.
Trends in real average household disposable income since 1999-00
This shows how average household disposable incomes have grown in ‘real terms’ (after inflation) in Australia between 1999-00 and 2015-16. During the boom period from 2000 to 2008, average household disposable income grew by a remarkable 4.3% per year in real terms. This reflected rapid overall economic growth underpinned by mining and housing booms. However, in 2008, the Global Financial Crisis cut economic growth by half. This reduced average disposable income slightly the following year. Average income then slowly increased, and dropped slightly again in 2015-16.
Profile of each income group by age
This graph shows the make-up of each income group by age. 2019-20: The largest age-group in every income group are 25-64 year olds, as they have a greater share of the population as a whole. However, the lowest income group comprises almost a third of older people, while they comprise only 8% of the highest income group. 2017-18: The largest age-group in every income group are 25-64 year olds, reflecting their greater share of the overall population. However, older individuals are over-represented (66%) in the lowest 40% income group, as are children aged under 15 (45%). Almost half (48%) of people of working age, 25-64 years, were in the highest 40% income group, reflecting that age group’s larger size and greater earning capacity. 2015-16: The largest age-group in every income group are 25-64 year olds. However, older individuals are over-represented (29%) in the lowest 20% income group, and children are over-represented (23%) in the second 20%. In contrast, individuals found in…
