Question

what is the main Criterion used by World Bank in classifying different countries what are the limitations of this Criterion if any

Answer 1

World Bank use the criterion of Per Capita income to classify different countries.
This is a narrow concept as it only sees the income of a country while literacy rate health facilities should also be included which are included in Human Development Index by UNDP.

Answer 2

Answer:

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 people in the individual countries. Two countries with the same per capita income might be very different with regard to income distribution. One might have equitable distribution of income while the other might have great disparities between the rich and the poor.
