High Quality Content by WIKIPEDIA articles! BIMARU was an acronym coined by taking the first letter of four northern Indian states : Bihar, Madhya Pradesh, Rajasthan, and Uttar Pradesh. Later Orissa was included resulting in BIMAROU. It was coined by Ashish Bose in the mid 1980s. BIMARU has a resemblance to a Hindi word "Bimar" which means sick. This was used to describe the bad state of economy in backward states Bihar, Madhya Pradesh, Rajasthan and Uttarpradesh. Later Orissa was included in the list. Several studies, including those by the UN, showed that the performance of the BIMARU states affected the GDP growth rate of India. Some of these states are also a part of Red Corridor. Since some of these states have now started to advance faster than some of the developed states, the concept of BIMARU is starting to become outdated.
