According to a new study regarding the increasing population worldwide, India’s population is expected to peak at 1.6 billion in 2048, after which it will steadily decline to 1.09 billion in 2100. The study also emphasizes that the decrease of the world’s population after the mid-century may also bring major changes in the global population and economic power.
Key Highlights Of The Study
The analysis published in the Lancet Journal uses data from the ‘Global Burden of Disease Study 2017’ to project future global, regional and national populations for countries including India, China, Japan, Italy and the United States. The study states that the world’s population will peak at 9.73 billion in 2064, after which it will shrink to 8.79 billion in 2100. According to researchers, India will have the world’s largest working-age population of 578 million in the world, followed by Nigeria, China and the US.
The study also predicts a change in the global age structure. By 2100, globally there would be 2.37 billion people aged above 65 years while 1.7 billion under 20 years. Although numbers of working-age adults in India are projected to fall from 762 million in 2017 to around 578 million in 2100, it is expected that India will have a greater role in Asia in taking steps to protect the working-age population.
The authors in their study also note some important limitations. While the study uses the best available data, predictions are constrained by the quantity and quality of past data. They also note that past trends are not always predictive of what will happen in the future.
