The VillageProjects.org site banner is a map that shows the percentage of  people in a country who live in poverty.

Poverty can also be defined as the following:

• A determined percentage of the population with the lowest income lives in poverty. According to this definition poverty keeps existing forever. Only the negative effects of poverty can be contested.
• Everyone who lives in poverty has less than a certain percentage of the average of the medium income. According to this definition poverty can be apart, through establishing minimum salaries. If those don’t exist the measure of poverty is independent from the spread of income.
