Messenger The Conversation is running a series, Class in Australia, to identify, illuminate and debate its many manifestations.
Here, Peter Whiteford investigates what has happened to income and wealth inequality in Australia in recent times. Australians like to think of themselves as egalitarian, and for much of our history we believed our income and wealth was spread around evenly. For many years, the world also shared that view.
From the s onwards, however, this view of Australia came under scrutiny. As historian John Hirst wrote: The most common measure of inequality is the Gini coefficientwhich varies between zero and one.
If everyone had exactly the same income then it would be zero perfect equality. If one household had all the income then it would be one complete inequality.

Trends in income inequality Working out what has happened to inequality in Australia over the long term is complex. While there is disagreement about overall trends, according to economists Andrew Leigh and Tony Atkinson, inequality declined between the s and the late s, with Peter Saunders identifying an increase in the s.
These long-run estimates are usually based either on wage trends or income tax data, which means that findings apply to individuals rather than households. Household incomes after benefits and taxes, however, are generally regarded as a better measure of economic resources.
Since the early s, the Australian Bureau of Statistics ABS has conducted regular high-quality surveys of household incomes. The most recent survey covers the year. Research by economists David Johnson and Roger Wilkins found that the Gini coefficient increased from around 0. Subsequently, the official ABS income statistics show that the Gini coefficient increased to 0.
Trends in income inequality Gini coefficient in Australia, —82 to Author The ABS points out that changes from year to year are sometimes not large enough to be statistically significant. Yet the cumulative picture is of an upward trend, punctuated with periods in which inequality has fallen.
Whether the most recent fall continues or is reversed remains to be seen. Trends in wealth inequality For many years, statistics on the distribution of wealth were even sparser than comprehensive statistics on the distribution of income.
So, it seems pretty clear that wealth is much more unequally distributed in Australia than income. This depends on how you look at it. The most recent Credit Suisse Global Wealth Reportprepared by Anthony Shorrocks, one of the most highly respected world experts on wealth distribution, estimates that the distribution of wealth in Australia is the second least unequal after Japan of 27 major countries and the 12th least unequal of countries.
It is also notable that the Credit Suisse report finds that Australia has the second highest average level of wealth in the world and the highest median wealth. Below is a map showing wealth inequality across the world.

The ABS survey — used by Credit Suisse — also presents two ways of looking at the distribution of wealth: These figures suggest that wealth is actually more equally distributed than income when the joint distribution of income and wealth is used - which is a more comprehensive measure of total household resources.
These two approaches yield remarkably different pictures of wealth distribution. This reflects the fact that people accumulate wealth over the course of their life.
As a result, older people have much higher average wealth than younger people, but older people generally have lower incomes than younger people. The answer is that most of the earlier studies were based on a limited income measure: If you are a full-time employed male wage earner in Australia, then you have a lower level of income inequality than in Denmarkotherwise one of the lowest inequality countries.
The most important source of inequality in Australia is whether you have a job or not. So the pillars of egalitarianism in Australia were high wages, high home ownership and low unemployment.
If we want to regain this position, we need to ensure that unemployment remains low and that low-income earners are able to buy into affordable housing.

How are they different? 2. DIFFERENT WORDS, SAME QUESTION Which is different? Write “both” inequalities. 3. In this lesson you will learn to create an inequality given a word problem by using algebraic reasoning.
Examples, solutions, videos, and worksheets to help Grade 6 students learn to write and explain inequality statements involving rational numbers. This guide serves to provide both a guided, extended reading list on analyzing social inequality (or stratification) and the syllabus for a graduate course based on the core of this extended reading list (over articles are included below).
For example, the inequality “50 ≥ the number of stars on any United States flag” is a true statement for every American flag ever flown—no flag has had over 50 stars. It holds true for the flag as it was designed in (13 stars, 50 ≥ 13), as it looked in (30 stars, 50 ≥ 30), and how we see it today (50 stars, 50 ≥ 50).
The important thing about inequalities is that there are multiple possible solutions. For example, the inequality “50 ≥ the number of stars on any United States flag” is a true statement for every American flag ever flown—no flag has had over 50 stars.
