By the year 2050, there will be some 9.7 billion people living on Earth, says a UN population report. However, the overall growth rate will continue to fall, and more countries will have to adapt to the consequences of an ageing population. “The World Population Prospects 2019: Highlights”, estimates that the next 30 years will see the global population add an extra 2 billion people to today’s figure of 7.7 billion, and, by the end of the century, the planet will have to sustain around 11 billion. India is expected to show the highest population increase between now and 2050, overtaking China as the world’s most populous country, by around 2027. India, along with eight other countries, will make up over half of the estimated population growth between now and 2050.
