Manufacturing or high-tech? This is what India's most prosperous states focus on

Roughly 40 per cent of India’s economic activity comes from Maharashtra, Gujarat, Tamil Nadu, and Karnataka, as per data from the National Accounts Statistics (NAS). The average prosperity level in these four states, measured in terms of per-person real income, is similar – around Rs 12,000-13,000 per month in 2018-19. For the rest of India, the same was only around Rs 7,600.
