India's population growth has been rapid since the 1950s. This was due to a combination of factors, including increased access to healthcare and improved economic development. This has resulted in a population growth from 361 million in 1951 to 1.37 billion in 2021, making India the second-most populous country in the world. The population is projected to reach 1.5 billion by 2030. As India's population continues to grow, its government needs to ensure that the necessary infrastructure and services are in place to support its population.
