Poverty is defined as when basic needs for food, clothing, and shelter are not being met. There are two main types of poverty: absolute poverty, defined as living on less than $1.25 per day; and relative poverty, defined as being poor compared to others within one's country. The rate of poverty varies greatly between countries, with some like Uganda having much higher rates than Norway. While poverty levels were much higher in 1990, affecting 47% of the world's population, significant reductions have occurred so that in 2010 only 22% of the world's people lived in poverty. However, outdated views of dividing countries into only two groups of developing vs. developed still persist despite changes in the world.
