The study throws light to the fact that fullfilment of social attributes of life and achievement of PCRGDP goes hand in hand. In other words, if one country reaches certain level of PCRGDP it is almost sure to attain certain level of social standard.
The importance of the study lies in its attempt to classify the countries on the basis of socio-economic aspects of life instead of only economic aspects of life.
The study once again picturises the phenomenon of regional concentration of the level of socio-economic development i.e. the peripherial effect is present.
