What is the definition of poverty?

There is no common definition for poverty that is accepted by all countries and organisations. Generally poverty refers to material deprivation and the state of being deficient in means of subsistence. What is more useful in defining poverty is to look at different measurements of poverty which is used. For example, the United Nations use the Human Poverty Index to rate the poverty of a country. There is also the Multidimensional Poverty Index used by the World Bank. Another measurement or index used is the Human Development Index, as well as the Human Deprivation Index. To complicate this further some measurements also focus on one aspect or group, like the Gender Poverty Index, the Gender Development Index or the Water Poverty Index. All of this shows that defining poverty is extremely complex as there is still no agreement on what poverty is exactly.
