wealth inequality

Wealth inequality shows up in a variety of ways. You can see it in the uneven distribution of millionaires around the world, and find it in the series of maps we published this time last year, which showed the average wealth per adult in each country. And it’s the same story when you look at median wealth per adult around the world

Wealth inequality is most often measured by the share of wealth owned by top wealth groups, or by the Gini coefficient, an index that reflects differences at all parts of the distribution, and which has a minimum value of zero (representing complete equality) and usually an upper bound of one. These indices usually follow a similar time path, but not always. When that happens, a more nuanced interpretation of the prevailing trends is required.

The evolution of wealth inequality this century for the world as a whole is a case in point. Estimates indicate that the share of the top 1% declined until the global financial crisis, then trended upwards until 2016, when it stabilised.

The top 1% currently own 45% of global net assets, down slightly from the 46,9% share in 2000. The Gini coefficient and the shares of the top 5% and 10% also declined between 2000 and 2008. But the trends have diverged from the top 1% pattern in

the post-crisis era. The share of the top 5%, for example, hardly changed, going from 70,6% in 2008 to 70,2% in 2019. This is 5,4 percentage points lower than the value in 2000. And the top 10% and Gini coefficient have continued to trend downwards.

The conclusion to be drawn is that – according to the latest data – global wealth gaps have generally narrowed over the past 20 years. The only group countering this trend is the upper tail, accounting for no more than 5% of the world’s population. The suggestion that most people have improved their relative wealth position is reinforced by the observation that the share of the bottom 90% of global wealth holders (portrayed in the graph as the gap between the top 10% share and the 100% upper line) rose from 11,5% in the year 2000 to 18,3% in 2019.

The best way to compare levels of wealth is by looking at median figures. A median number simply indicates that 50% of all people have more than that

Venezuela might be in worse shape, but given the economic instability, researchers could not provide an accurate estimate. 5.
