Rising inequality is a worldwide phenomena.
Inequality is also rising in affluent countries such as the United States and in rapidly developing nations such as China.
For an excellent visual treatment of World development data see GapMinder. Here are some highlights on one of the presentations on World Income Distribution:
- The richest 20% have 74% of income
- The poorest 20% have 2% of income
- In 2000, 1.2 billion people or 19% of world population lived on less then $1 per day
- In 1970, 1.4 billion or 38% of world population lived on less then $1 per day.
- In Africa, in 2000, 66% lived on less the $1 per day. This compares to 11% in 1970.
