According to the 27th edition of the United Nations’ World Population Prospects, 2022, India is projected to surpass China as the world’s most populous country in 2023. Key Notes- : The world’s population is projected to reach 8 billion on 15 November 2022. The latest projections by the United Nations suggest that the global population could grow to around 8.5 billion in 2030, 9.7 billion in 2050 and 10.4 billion in 2100. In 2021, the average fertility of the world’s population stood at 2.3 births per woman. In 2022, the two most populous regions were both in Asia: Eastern and South-Eastern Asia with 2.3 billion people (29 per cent of the global population), and Central and Southern Asia with 2.1 billion (26 per cent). China and India, with more than 1.4 billion each, accounted for most of the population in these two regions. More than half of the projected increase in global population up to 2050 will be concentrated in just eight countries: the Democratic Republic of the Congo, Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines and the United Republic of Tanzania. Disparate growth rates among the world’s largest countries will re-order their ranking by size.
