This chart shows the real value (after inflation is taken into account) of average wealth holdings of each wealth group, compared over time.
As with income inequality, changes in wealth inequality were driven mainly by the highest 20% wealth group, although this growth was more volatile than for middle and low wealth groups. This was due in part to the greater share of the wealth of the highest 20% held in financial assets such as shares.
The average household wealth of the highest 20% rose from $1.9 million in 2003-04 to $2.6 million in 2009-10, declined to $2.4 million in 2011-12 and rose again to $3.255 million in 2017-18.
