The multidimensional poverty index: "The index seeks to build up a picture of the prevalence of poverty based on the fraction of households who lack certain basic things. Some of these are material. Does a family home have a dirt or dung floor? Does it lack a decent toilet? Must members of the household travel more than 30 minutes on foot to get clean water to drink? Do they live without electricity? Others relate to education, such as whether any school-age children are not enrolled or whether nobody in the family has finished primary school. Still others concern health, such as whether any member of a household is malnourished. A household is counted as poor if it is deprived on over 30% of the ten indicators used. Researchers can then calculate the percentage of people in each country who are “multidimensionally poor”."
