INTRODUCTION

This data story uses Australian Bureau of Statistics household income and wealth data to examine whether economic prosperity is shared equally across Australian households. The story follows five connected patterns: household wealth growth, wealth concentration, income differences, asset ownership and financial stress. The visualisations are presented in a narrative format inspired by data stories published by The Conversation.

Data source: Australian Bureau of Statistics (ABS), Household Income and Wealth, Australia: Summary of Results, 2019–20.

Together, these visualisations provide insight into whether Australia’s economic growth has translated into broadly shared prosperity or increasing inequality.

Australian household wealth has increased over time

Average household net worth increased substantially between 2009–10 and 2019–20. Although there was a small decline in 2011–12, wealth generally trended upward throughout the decade. This suggests that Australian households accumulated greater levels of wealth over time.

The wealth gap has persisted over time

The wealth gap remained large across the decade. While all quintiles experienced some movement in mean net worth, the highest wealth quintile consistently remained far above the rest of the population. This shows that national wealth growth did not remove the underlying concentration of household wealth.

Wealth and income rise together

Income increases consistently with household wealth. Households in the highest wealth quintile earn considerably more income than those in lower quintiles. This relationship suggests that wealth accumulation and income generation reinforce one another.

Property and financial assets are concentrated among wealthier households

Property and financial asset ownership rise sharply across wealth quintiles. Wealthier households possess substantially larger asset portfolios, particularly in property holdings. This contributes to the persistence of wealth inequality over time.

Lower-income households are less financially resilient

Financial stress is much higher among lower-income households. The lowest income quintile reports higher difficulty across several stress indicators, including raising emergency funds and paying bills on time. This shows that the consequences of unequal wealth and income are experienced most directly by households with fewer financial resources.

KEY INSIGHTS

Australian households experienced substantial wealth growth between 2009–10 and 2019–20. However, the gains were distributed unevenly across the population. The highest wealth quintile held the majority of household wealth, earned considerably higher incomes and owned substantially more financial and property assets. In contrast, lower-income households faced greater financial vulnerability and were less able to manage unexpected expenses. These findings suggest that although Australia became wealthier overall, the benefits of that growth were not distributed equally, leaving lower-income households more vulnerable to financial stress.

CONCLUSION

Australia remains a wealthy country, but this data story shows that prosperity is not experienced equally. Household wealth increased over time, yet the highest wealth groups continued to hold a much larger share of resources. These households also earned more income and owned substantially greater financial and property assets. At the other end of the distribution, lower-income households were more exposed to financial stress and less able to manage unexpected costs. In this sense, Australia may still be the lucky country for some households, but not for everyone. Addressing these disparities remains an important challenge for policymakers seeking inclusive economic growth.

ACKNOWLEDGEMENTS

This data story was inspired by the narrative visualisation style commonly used by The Conversation, particularly articles that communicate social and economic trends through a sequence of connected charts. The data, analysis, visualisations and interpretations presented in this report were developed independently using Australian Bureau of Statistics data.
