WebThe poverty-gap index measures the depth of poverty and is defined by the mean distance below the poverty threshold, where the mean is formed over the entire population (the nonpoor are counted as having zero poverty gap). In other words, the index can be used as an aggregate poverty measure, as well as decomposed for various sub-groups of the population, such as by region, employment sector, education level, gender, age or ethnic group.

Summarizing the information on the different deprivations into a single index proves useful in making comparisons across populations and across time. Our World in Data is free and accessible for everyone. Our World In Data is a project of the Global Change Data Lab, a registered charity in England and Wales (Charity Number 1186433). For all countries apart from the US, we take the harmonized poverty line calculated by Jolliffe et al. We provide a wide array of financial products and technical assistance, and we help countries share and apply innovative knowledge and solutions to the challenges they face.

Indicators are chosen for each dimension on the principles of accuracy (using as many indicators as necessary so that analysis can properly guide policy) and parsimony (using as few indicators as possible to ensure ease of analysis for policy purposes and transparency). In this calculation, individuals whose income is above the poverty line have a gap of zero. P formula raises the summands to the power alpha, so that FGT0 is the head count index, FGT1 the PGI and FGT2 the squared PGI.
