India’s growing power will reshape the world as we know it. India’s real GDP has surged by an annual average of nearly 9% in the past five years, and across all measures of influence—from military might to diplomatic sway to economic weight—the country’s clout will continue to strengthen. India is on track to be the fastest-growing economy in the world in 2008-30, averaging annual expansion of 6.3%. It will also overtake China to become the most populous country in the early 2030s.
