The world is about to get more crowded, according to a new report prepared by the United Nations, with the planet’s population expected to climb to nearly 10 billion by 2050.
The UN’s World Population Prospects 2019, published on Tuesday, projected that the next three decades will see today’s figure of 7.7 billion people rise to 9.7 billion by 2050 despite a continued slowdown in the global birth rate. According to Aljazeera, more than half of the increase will be concentrated in just nine countries – India, Nigeria, Pakistan, the Democratic Republic of Congo, Ethiopia, Tanzania, Indonesia, Egypt and the United States – while the population of sub-Saharan Africa is projected to nearly double.
China, with 1.43 billion people in 2019, and India, with 1.37 billion, have long been the two most populous countries of the world, comprising 19 and 18 per cent, respectively, of the global total in 2019. The report also says that India is projected to surpass China as the world’s most populous country in the next eight years. According to it, India is expected to add nearly 273 million people between 2019 and 2050 and remain the most populated country through the end of the current century.
India is expected to add nearly 273 million people between 2019 and 2050, while the population of Nigeria is projected to grow by 200 million. Together, these two countries could account for 23 per cent of the global population increase to 2050, according to report.
According to India Today, the report also stated that the world’s population is growing older due to increasing life expectancy and falling fertility levels, and that the number of countries experiencing a reduction in population size is growing.
By 2050, one in six people in the world will be over age 65 (16 per cent), up from one in 11 in 2019 (9 per cent). The number of persons aged 80 years or over is projected to triple, from 143 million in 2019 to 426 million in 2050.
