Calculation of National Income of India: A Brief History

It will be fascinating for you to know that the first effort to calculate National Income of India was made by Dadabhai Naroji in 1867-68. This was followed by various other techniques. The first scientific technique was formulated by Prof. V.K.R Rao in 1931-32. However, this was not very satisfactory. The first official effort was made by Prof. P. C.
