This from the Financial Times:

Personal wealth is distributed so unevenly across the world that the richest two per cent of adults own more than 50 per cent of the world’s assets while the poorest half hold only 1 per cent of wealth…

To belong to the top 1 per cent of the world’s wealthiest adults you would need more than $500,000, something that 37m adults have achieved.

So much of the world’s wealth is concentrated in few hands that if all the world’s wealth was distributed evenly, each person would have $20,500 of assets to use.

Almost 90 per cent of the world’s wealth is held in North America, Europe and high-income Asian and Pacific countries, such as Japan and Australia.

While North America has 6 per cent of the world’s adult population, it accounts for 34 per cent of household wealth.

The concentration of wealth in different countries varies considerably, with the top 10 per cent in the US holding 70 per cent of the country’s wealth, compared with 61 per cent in France, 56 per cent in the UK, 44 per cent in Germany and 39 per cent in Japan.
