As seen in the trend line in the graph, the slope of the line seems to be constant, which means the population growth of India is constant. This could be due to India currently developing as a country as its population almost doubled in the last 30 years from 1980 to 2010. It's predicted that India's population will surpass China's population in 10-15 years, which means India will soon become the most populous country in the world as China is currently the most populous country in the world.
