As per the methodology of the Suresh Tendulkar Committee report, the population below the poverty line in India was 35.4 million (29.6% of the population) in 2009-2010 and was 69 million (21.9% of the population) in 2011–2012. In 2014, the Rangarajan Committee said that the population below the poverty line was 454 million (38.2% of the population) in 2009-2010 and was 363 million (29.5% of the population) in 2011–2012. Deutsche Bank Research estimated that there are nearly 300 million people who are in the middle class. If these previous trends continue, India's share of world GDP will significantly increase from 7.3% in 2016 to 8.5% by 2020. In 2012, around 170 million people, or 12.4% of India's population, lived in poverty (defined as $1.90 (Rs 123.5)), an improvement from 29.8% of India's population in 2009. In their paper, economists Sandhya Krishnan and Neeraj Hatekar conclude that 600 million people, or more than half of India's population, belong to the middle class.
