India is projected to overtake the US to become the world's second-largest economy by 2075, according to Goldman Sachs Research. India's GDP is expected to grow from $2.8tn in 2020 to $52.5tn in 2075, surpassing Japan and Germany on the way. The research notes that innovation and increasing worker productivity will be important factors in India's growth, and that the country's large and educated population is vital. The labour force participation rate, particularly among women, will be a key part of achieving this growth, as will increased investment and deeper financial sector development.
