The concept of human capital has relatively more importance in labour surplus countries. The surplus-labour in these countries is the human resource available in more abundance than the tangible capital resource. The problem of scarcity of tangible capital in the labour surplus countries can be resolved by accelerating the rate of human capital formation with both private and public investment in the education and health sectors of their national economies. The statistical indicator of estimating human development in each nation is Human Development Index (HDI). It is the combination of the 'Life Expectancy Index', 'Education Index' and 'Income Index'. Human capital is the backbone of human development and economic development in every nation.
