Before independence, estimates of national income in India were not collected officially so that the Indians could not realise the stagnancy of the Indian economy, but even during the British period, several economists performed estimates of national income and per capita income. Dadabhai Naoraji was the first person to perform the estimates of national income. He presented the national income estimates of 1867-68 in the year 1876. Dr. V.K.R.V. Rao made the necessary amendments in these estimates in an effort to make them more useful for comparative analysis.
