This estimation also reveals that India is expected to add 273 million population by 2050 and will remain the most populated until the end of the century.
The report stated that in 2019, India has an estimated 1.37 billion people’s strength and China 1.43 billion and by 2027, India’s population is projected to surpass China’s.
The Population Division of the UN Department of Economic and Social Affairs published that ‘The World Population Prospects 2019’. According to this report, the global population is projected to increase by another 2 billion people by 2050, from 7.7 billion in 2019 to 9.7 billion thirty years down the line.
Between now and 2050, 55 countries are estimated to see their populations shrink by at least 1%. Incidentally, since 2010, 27 countries have recorded a minimum 1% reduction in it.
This trend of a growing number of countries experiencing a decline in the number of people has been attributed to sustained low levels of fertility and, in some cases, high rates of emigration. In China, the largest of these 55 countries, it is projected to shrink by as much as 2.2% or 31.4 million by 2050.
In the same period, India is expected to add 273 million people more to its headcount. India leads the set of nine countries that will make up for more than half the projected growth of the global number of people by 2050.
Following the India-China re-ordering in 2027, the ranking of the five largest countries is projected to remain the same until the end of the century.
India is expected to remain the world’s most populous country with nearly 1.5 billion inhabitants, followed by China at 1.1 billion, Nigeria with 733 million, the United States with 434 million, and Pakistan with an estimated people of 403 million.
Overall, it states, the world’s occupiers are aging, with the age group of 65 and above growing at such a fast rate that by 2050, one in six people in the world will be part of it as compared to one in 11 in 2019.
By the end of the century, world occupiers are set to peak at a level of about 11 billion.
