The PIP Methodology Handbook provides a good summary of the comparability and data quality issues affecting this data and how it tries to address them.In collating this survey data the World Bank takes a range of steps to harmonize it where possible, but comparability issues remain. In practice, it may be useful to calculate the measure for several values of k. Robustness checks can be performed across all values of k. In the example in Table 1, k is set to 4 and the persons whose data are shaded are identified as poor. In 2015, this threshold was updated from $1.25 to $1.90 per day.

The PIP Methodology Handbook provides a good summary of the comparability and data quality issues affecting this data and how it tries to address them. Global poverty data relies on national household surveys that have differences affecting their comparability across countries or over time. The idea behind measuring poverty in relative terms is that a persons well-being depends not on their own absolute standard of living but on how that standard compares with some reference group, or whether it enables them to participate in the norms and customs of their society. In van Zanden, Rijpma, Malinowski and Mira dErcole (eds.)

Over the past two centuries the world made good progress against extreme poverty. T Then an average increase of $25 per individual per year would eliminate extreme poverty. The fact that rapid progress against poverty has been achieved in many places is one of the most important lessons we can learn from the available data on extreme poverty. For example, suppose a country has 10 million individuals, a poverty line of $500 per year and a poverty gap index of 5%. (2022). W A deprivationcutoff is set for each indicator.

In collating this survey data the World Bank takes a range of steps to harmonize it where possible, but comparability issues remain. By squaring each poverty gap data, the measure puts more weight the further a poor person's observed income falls below the poverty line. 2. The first 6 steps are common to many multidimensional poverty measures; the remainder are specific to the Alkire Foster method. 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.You can read more in our article From $1.90 to $2.15 a day: the updated International Poverty Line.

Along with data for individual countries, the World Bank also provides global and regional poverty estimates which aggregate over the available country data. A = (4/6 + 6/6)/2 = 5/6. To help communicate the latter, the World Bank produces a variable that groups surveys within each individual country into more comparable spells.
