UN Secretary-General António Guterres said, “This year’s World Population Day falls during a milestone year, when we anticipate the birth of Earth’s 8 billionth inhabitant. This is an occasion to celebrate our diversity, recognise our common humanity, and marvel at advancements in health that have extended lifespans and dramatically reduced maternal and child mortality rates. ” “It is (also) a reminder of our shared responsibility to care for our planet and a moment to reflect on where we still fall short of our commitments to one another,” he said. The world’s two most populous regions in 2022 were Eastern and South-Eastern Asia, with 2.3 billion people, representing 29% of the global population, and Central and Southern Asia , with 2.1 billion, representing 26% of the total world population. China and India accounted for the largest populations in these regions, with more than 1.4 billion each in 2022. More than half of the projected increase in global population up to 2050 will be concentrated in just eight countries of the Democratic Republic of the Congo, Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines and Tanzania.
“Disparate population growth rates among the world’s largest countries will change their ranking by size: for example, India is projected to surpass China as the world’s most populous country in 2023,” the UN report said. According to the report, India’s population stands at 1.412 billion in 2022, against China’s 1.426 billion.
India, which will surpass China as the world’s most populous nation by 2023, is projected to have a population of 1.668 billion in 2050, way ahead of China’s 1.317 billion people by the middle of the century. The report added that it is estimated 10 countries experienced a net outflow of over 1 million migrants between 2010 and 2021.
