The figure below depicts the trend regarding the population growth of India and China in the first half of the 21st century.
An increase in population was noticed in both China and India in the past 20 years. Starting with 1.25 billion in 2000, China was more populous compared to India. Meanwhile, there were only a billion people in India. A moderate upsurge was then shown, reaching a current level of 1.4 billion in 2020. While in India, a steeper increase was shown at the same time, attaining 1.32 billion in 2020. Despite a sharp increase, India still has a smaller population size than China now.
The predicted trend of population growth of the mentioned countries will diverge to different trajectories in the future. The population of China will decline minimally, followed by the peak in 2030 with a population just over 1.4 billion. However, the steep growth will still continue in India. It will surpass China in 2030 and reach the final level of 1.6 billion in 2050.
Although both countries have experienced a population surge in the past 20 years, the trend of population changes is predicted to diverge in the future. On the other hand, it is noted that China has a more stable population change compared to India.
