Normalized Poverty gap (NPG)= APG / YpAverage Income shortfall (AIS) = the total poverty gap divided by the headcount of the poor: AIS = TPG/ H. It tells us by which amount the income of a poor person falls below the poverty line.

The Sen capability approach is a moral framework. It proposes that social arrangements should be evaluated primarily according to the extent of freedom people have to promote as well as achieving functions they value. Such as those of social justice or the narratives of development ethics.

The Headcount Index is calculated by taking the total number of people in a country who fall below a predetermined income level and dividing this figure by the total population. In other words, the Headcount Index is simply the percentage of the population that falls below the official poverty line.

Ratio of average counts per pixel in the liver ROI and mid-thigh ROI was calculated and recorded as hepatic to thigh ratio (HTR). The hepatic to thigh ratio is meant to correct hepatic uptake for background counts.

Definition: National poverty headcount ratio is the percentage of the population living below the national poverty lines. National estimates are based on population-weighted subgroup estimates from household surveys.

The head count ratio (HCR) is the population proportion that exists, or lives, below the poverty threshold.

What Is the Poverty Gap? The poverty gap is a ratio showing the average shortfall of the total population from the poverty line—the minimum level of income required to secure the basic necessities for survival. In other words, it reflects the intensity of poverty in a nation.

Step 4, instead, requires that we count the poor and divide their number by the total population. This is the headcount ratio. Figure 2 illustrates the steps needed to calculate the poverty gap.

The poverty gap is the ratio by which the mean income of the poor falls below the poverty line. The poverty line is defined as half the median household income of the total population.

Sen’s interest in alternative poverty measures began in the late 1950s at the University of Cambridge, when he and fellow student Mahbub ul Haq (later a policy director at the World Bank and Pakistan’s minister of finance) began discussing an alternative to the GDP per capita benchmark.
