Indeed, almost four out of 10 (39 percent) multidimensionally poor persons are not captured by monetary poverty because they are deprived in nonmonetary dimensions alone. Such surveys are designed with cross-country comparability in mind, but because the surveys reflect the circumstances and priorities of individual countries at the time of the survey, there are some important differences. By comparing the monetary poverty dimension with indicators from other dimensions, it is possible to form a picture of how many multidimensionally poor are not captured by monetary poverty, as well as which indicator deprivations most affect well-being in the different regions (See Table 2). Such surveys are partly designed with cross-country comparability in mind, but because the surveys reflect the circumstances and priorities of individual countries at the time of the survey, there are some important differences. You can read more about how the World Bank sets these higher poverty lines, as well as the International Poverty Line against which it measures extreme poverty, in our article From $1.90 to $2.15 a day: the updated International Poverty Line.

Our Data Explorer provides the option of viewing the data with these breaks in comparability indicated, and these spells are also indicated in our data download. The two concepts are closely related: the income of a household equals their consumption plus any saving, or minus any borrowing or spending out of savings.One important difference is that, while zero consumption is not a feasible value people with zero consumption would starve a zero income is a feasible value. Global poverty data relies on national household surveys that have differences affecting their comparability across countries or over time. In 2019, the U.S. poverty gap totaled $154 billion, meaning $154 billion was needed that year to end poverty in the country. A higher poverty gap index means that poverty is more severe. In such a case, anaverage increase of $25 per individual, per year, would eliminate extreme poverty. These are mapped into three dimensions of well-being: monetary, education, and basic infrastructure services. You can read more about the interpolation methods used by the World Bank in Chapter 5 of the Poverty and Inequality Platform Methodology Handbook. But in a world where price differences across countries and over time are large it is important to attempt to account for these differences as well as possible, and this is what these adjustments do. The majority of the poorest now live in Sub-Saharan Africa, where weaker economic growth and high population growth in many countries has led to a rising number of people living in extreme poverty.

Shown are those countries with a decline of more than 30 percentage points over a period of 15 years or more.There are a number of ways in which comparability across the different household surveys on which this data is based can be limited. where The intentional poverty line is a metric used globally to determine if an individual is considered to be living in poverty. No adult in the household (age of grade 9 or above) has completed primary education. Our understanding of the extent of poverty and how it is changing depends on which definition we have in mind.
