The ABS is wrong: inequality is getting worse in Australia – Christopher Sheil and Frank Stilwell

The Australian Bureau of Statistics announced in September 2017 that “inequality has remained stable since 2013-4”. Given that economic inequality has been increasing since 1980 and the widespread view that it has reached unacceptable levels, the ABS’s report came as a welcome respite. Or did it?

Most public discussion about inequality focuses on income (an economic flow), but wealth (an economic assets stock) is a more fundamental indicator of people’s social position and opportunities, and its distribution goes to the fairness and stability of a society.

The ABS reports that the share of Australia’s household wealth owned by the richest quintile (the top 20 per cent) has increased from 62.1 to 62.5 per cent since 2013-14.

An increase of just 0.4 per cent looks small, until you realise that’s equal to half the total wealth owned by the poorest 20 per cent of households, whose share of the total wealth has fallen from 0.9 to 0.8 per cent. Wealth inequality thus continues to increase at the extremes.

The share owned by the second richest quintile has fallen very slightly, from 20.5 to 20.4 per cent, while the middle and second lowest quintiles are unchanged.

The problem with the Gini coefficient

These shifts were not large enough to change the size of the Gini coefficient, the basis on which the ABS concluded that inequality has stabilised.

The Gini coefficient is a statistical artefact that aims to rank the distribution between complete equality (where everyone owns the same wealth) and complete inequality (where one house- hold owns the lot). As a widely used index, it can hide as much as it reveals.

In this case, the stability of the Gini appears anomalous, given the very large rises in the value of houses in Australian cities during recent years and the fact that few among the poorest 40 per cent own one.

Most of the wealth the ABS apportions to the bottom of the wealth distribution comprises non-income earning house- hold durables (such as cars, furniture and clothing), assets that are valued at zero in the national accounts (which treats durables as consumed when they’re bought).

The quite poor and the quite rich

So, what’s really going on? The best glimpse provided by the ABS’s survey is a figure called the P90/P10 ratio. This refers to the wealth of those households at the 10th percentile (measured from the bottom of the range) divided into the wealth of the 90th percentile (the 10th percentile measured from the top). In other words, it compares the comparative wealth of the quite poor and the quite rich, but not the most extreme cases.

The ABS reports that the wealth of those on the 90th percentile is now almost $2 million, about 60 times the wealth of households at the 10th percentile.

The multiple is up from 52 times in 2013-14, a rise of 13.2 per cent, which is the biggest jump in this ratio since the ABS began surveying wealth (in 2003- 04, when the P90/P10 ratio was 45).

The increase in this ratio implies that the gains of the wealthiest 10 per cent of households have been greater than those accumulated by the top quintile overall, a scenario reinforced by the facts that the top quintile’s average wealth rose by a lower 12% cent, and this average was itself almost a cool million higher than the $2 million entry point for the top 10% ($2.9 million).

In other words, despite the apparent stability of the quintile distribution, the survey results are compatible with other evidence that the wealth of the top 10% – particularly the top 1% – is continuing to race away from the rest of us.

Concentration of wealth is increasing

The limitation of the ABS survey is that it ignores what is happening to the wealth distribution beyond the 90th percentile, which is precisely where most of the concern about growing inequality lies. The methodology lags behind international best practice, which now routinely shows data for the top 1 per cent, the top 10 per cent and the bottom 50 per cent.

Last year when we prepared a report on Australian wealth inequality for the Evatt Foundation, we adopted the global standards, using OECD data and, ironically, ABS data supplied to the OECD not published in Australia.

On conservative assumptions, we found that the top 10 per cent of households owned at least 50 per cent of the total wealth, and the top 1 per cent owned at least 15 per cent.

There is nothing in the ABS survey that leads us to conclude other than that the concentration of wealth in Australia is probably still increasing. If our official statistician thinks inequality has stabilis- ed, he should adopt the methodology to prove it.
