Below is graphic from ANZ Bank showing the change in real income between 1988 and 2008 at various percentiles of global income distribution (calculated in 2005 international dollars). Global inequality has improved except for the upper middle class.
Some comparisons of income distribution:
- An American having the average income of the bottom U.S. decile is better-off than 2/3 of world population.
- The richest 1% of people in the world receive as much as the bottom 57%, or in other words, less than 50 million richest people receive as much as 2.7 billion poor.
- The three richest people possess more financial assets than the poorest 10% of the world’s population, combined.
- In 2005, the three richest people in the world have total assets that exceed the annual combined GDP of the 47 countries with the least GDP.
- In 2005, the 125 richest people in the world have assets that exceed the annual combined GDP of all the least developed countries.
- In January this year Oxfam calculated that the eight richest men in the world own the same wealth as the 3.6 billion people who make up the poorest half of humanity.
The world’s 8 richest people are, in order of net worth:
1. Bill Gates: America founder of Microsoft (net worth $75 billion)
2. Amancio Ortega: Spanish founder of Inditex which owns the Zara fashion chain (net worth $67 billion)
