Another Expert Group was instituted in 1993, chaired by Lakdawala, to examine poverty line for India. It recommended that regional economic differences are large enough that poverty lines should be calculated for each state. From then on, a standard list of commodities were drawn up and priced in each state of the nation, using 1973–74 as a base year. This basket of goods could then be re-priced each year and comparisons made between regions. The Government of India began using a modified version of this method of calculating the poverty line in India.
