- At the current rate of growth, India's population is likely to peak by 2047 at about 1.61 billion and then decline to 1.03 billion by 2100.
- However, were it to meet UN Sustainable Goal Development targets, the peak would be earlier and see a population decline to 929 million.
- India will, however, remain the most populous country. The five largest countries in 2100 (are projected) to be India, Nigeria, China, the U.S., and Pakistan.
