The fraction of people within a country experiencing absolute poverty is a function of the production capacity of the country and the wealth distribution within the country.
The conditions regarding wealth and equity within a country may be reflected in a number of indicators, some possible indicators are presented here.
If poverty is a matter of development, the fraction of literacy may be a valid indicator. This factor reflects the educational level, depending on the existence and availability of schools and other educational institutions.
Access to other public good resources also reflects the environmental context where economic growth may take place. Here I include indirectly two types of public goods, relative to population size: Electric consumption and total length of paved roads.
Another possible indicator is the relative quantity of a commodity that used to be a public good, now a private good: Mobile phones (substituting phones).
The figures have been constructed by the use of the function CountryData in Mathematica (C) by Arne Eide
