By 2023, India will take away the title of the most populous country in the world from China, according to IFL Science, citing a new UN report.. In addition, this report predicts that on November 15, 2022, the world's population will exceed eight billion people..

However, it notes that the population boom is ending as the population is now growing at the slowest rate since the 1950s.. According to forecasts, by 2030 the world's population will grow to 8.5 billion, to 9.7 billion in 2050 and to 10.4 billion by 2100..

It is noted that more than half of the population growth projected by 2050 will be concentrated in just eight countries: the Democratic Republic of the Congo, Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines and Tanzania.

Most of the 46 least developed countries are among the fastest growing countries. The population of these countries is projected to double between 2022 and 2050. However, 61 countries, including a significant part of Europe, will experience a decline in population over the same period..

At the moment, the population of China is estimated at 1.426 billion people, and India - 1.412 billion.. India's population is expected to continue to grow and reach 1.668 billion by 2050. In China, by contrast, the population will decline and reach about 1.317 billion by mid-century..

There are currently more men in the world than women: 50.3% and 49.7% respectively. But it is expected that by 2050 the number of women and men will equal.

The number of people aged 65 and over is projected to increase from 2022 to 2050. At the moment they make up 10% of the world population, but this figure will increase to 12% in 2030 and up to 16% in 2050. This trend will be particularly strong in Europe and North America, where one in four people will be over 65 by 2050..
