The poverty gap index is an improvement over the poverty measure head count ratio, which simply counts all the people below a poverty line in a given population and considers them equally poor. [2] Poverty gap index estimates the depth of poverty by considering how far the poor are from that poverty line on average. [3] The poverty gap index ...
The most commonly used index from the family, FGT 2, puts higher weight on the poverty of the poorest individuals, making it a combined measure of poverty and income inequality and a popular choice within development economics. The indices were introduced in a 1984 paper by economists Erik Thorbecke, Joel Greer, and James Foster. [1] [2]
Head count ratio in South Africa. The head count ratio (HCR) is the population proportion that exists, or lives, below the poverty threshold. [1] One of the undesirable features of the head count ratio is that it ignores the depth of poverty; if the poor become poorer, the head count index does not change. [2]
According to World Bank, "Poverty headcount ratio at a defined value a day is the percentage of the population living on less than that value a day at 2017 purchasing power adjusted prices. As a result of revisions in PPP exchange rates, poverty rates for individual countries cannot be compared with poverty rates reported in earlier editions."
Adjusted headcount ratio (M0), otherwise known as the MPI: This measure reflects both the incidence of poverty (the percentage of the population who are poor) and the intensity of poverty (the percentage of deprivations suffered by each person or household on average). M0 is calculated by multiplying the incidence (H) by the intensity (A). M0 ...

When measured, poverty may be absolute or relative.Absolute poverty refers to a set standard which is consistent over time and between countries. An example of an absolute measurement would be the percentage of the population eating less food than is required to sustain the human body (approximately 2000–2500 calories per day).
Sen poverty measure combines the Gini coefficient for people living below the poverty line with headcount ration of poverty and the average income of these below the poverty line. [20] This measure has been developed by Nobel Prize winner Amartya Sen but has not yet been used in the field of income inequality hypothesis.
