In 2002, an estimated 17% of the world population lived on this amount. They lived on less than or equal to what, to be precise, US$1.08 would have bought in the United States in 1993.
In over twenty territories more than a third of the population lives on less than US$1 a day. All but two of these territories are in Africa.
The largest population living on US$1 a day is in Southern Asia, most of whom live in India.
Absolute poverty is defined as living on the equivalent of US$2 a day or less. In 2002, 43% of the world population lived on this little. This money has to cover the basics of food, shelter and water. Medicines, new clothing, and school books would not be on the priority list.
When almost an entire population lives on this little, it is unsurprising if undernourishment is high, education levels are low, and life expectancy short. In both Nigeria and Mali, 9 of every ten people survives on less than US$2 a day.
South America has a relatively small poor population, yet 39 million people have less than US$2 a day in Brazil.
Territory size shows the proportion of all people living on less than or equal to US$2 in purchasing power parity a day.
In 2002, 53 million people in the world lived in households in receipt of US$200 purchasing power parity (PPP) per day. Of these high earners, 58% lived in the United States.
Western Europe and South America are also home to quite large populations of high earners. Within Western Europe the most very high earners live in the United Kingdom, Italy and France. The highest earners of South America live primarily in Brazil and Argentina.
Few very high earners live in Southern Asia, Northern Africa, Eastern Europe and Central Africa.
Territory size shows the proportion of all people living on over PPP US$ 200 a day worldwide, that live there.
