Poverty has been a very common situation in rural countries and areas. Families and children struggle to put food on their plates and starve to death. World Organization describes poverty like this: "Poverty is hunger. ... These are all costs of being poor." Poverty has many faces, changing from place to place and across time, and has been described in many ways.  Most often, poverty is a situation people want to escape.
