After the independence of India, West Bengal was still dependent on the central government for meeting its demands for food as production remained stagnant and the Green Revolution bypassed the state. However, there has been a significant spurt in food production since the 1980s. The state is now one of the few with a surplus, producing nearly 20% of the rice and 33% of the potato yield in 2004, despite accounting for only 7.55% of the total population of India. Total export from IT sector of the state is estimated to have crossed 22,897 crore (US$3.28 billion) in 2018–19.
