Physical quality of life index: Some international and Indian applications

In this paper, an attempt has been made to construct the physical quality of life index (PQLI) for some countries and for the Indian States as well. Three important indicators, viz. literacy rate, infant mortality rate and life expectancy at birth, reflecting the quality of life have been chosen and combined with equal weights to obtain PQLI. The rationale of equal weights, apart from any subjective judgement, may also be found in a mathematical model presented here. It is observed that PQLI rises sharply with per capita GNP but after a certain stage, an increase of per capita GNP is not accompanied by an increase of PQLI.
