Question

what criterior world bank has used to comparedevelopment of different

Answer 1

The main criterion used by the World Bank in classifying different countries is the per capita income or average income of a person in a country.  Limitations of this criterion:  It does not tell us about how this average income is distributed among the peoplein the individual countries. Two countries with the same per capita income might be very differentwith regard toincome distribution. One might have equitable distribution of incomewhile the other might have great disparities between the rich and the poor.
