Poverty is a state or condition in which an individual lacks the financial resources and essentials for a basic standard of living. Poverty can have diverse environmental, legal, social, economic, and political causes and effects. When evaluating poverty in statistics or economics there are two main measures: absolute poverty which compares income against the amount needed to meet basic personal needs, such as food, clothing, and shelter; secondly, relative poverty measures when a person cannot meet a minimum level of living standards, compared to others in the same time and place.
