According to the research, India's population will be 1.412 billion in 2022, compared to China's 1.426 billion.
According to a United Nations research released on Monday, India is expected to overtake China as the world's most populated nation next year. The report also predicted that the world's population would hit eight billion by mid-November 2022.
According to the World Population Prospects 2022 report from the Population Division of the UN Department of Economic and Social Affairs, the world's population is expected to exceed eight billion on November 15, 2022.
In 2020, the world's population decreased by less than 1%, rising at its sluggish rate since 1950.
According to the United Nations' most recent estimates, the world's population may reach 8.5 billion people in 2030 and 9.7 billion by 2050.
The population is predicted to peak at 10.4 billion people in the 2080s and stay there until 2100.
"This year's World Population Day [July 11] occurs in a historic year in which we look forward to welcoming the eighth billionth person to the planet. According to U.N. Secretary-General António Guterres, this is a time to celebrate our differences, acknowledge our shared humanity, and marvel at medical advances that have lengthened life expectancies and significantly decreased maternal and infant death rates.
At the same time, he continued, "it is an opportunity to reflect on where we still fall short of our obligations to one another and a reminder of our shared responsibility to care for our planet."
In 2023, India is expected to overtake China as the world's most populated nation, according to the research.
Eastern and South-Eastern Asia had 2.3 billion people, or 29% of the world's population, while Central and Southern Asia had 2.1 billion, or 26% of the world's population, making them the two most populated areas in 2022.
With more than 1.4 billion people apiece, China and India had the greatest populations in these areas in 2022.
Just eight nations—the Democratic Republic of the Congo, Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines, and Tanzania—will account for more than half of the predicted growth in the world's population by 2050.
Different rates of population increase among the world's major nations will affect how they rank in terms of size. For instance, India is anticipated to overtake China as the most populated nation in 2023.
In 2022, India would have 1.412 billion people, compared to China's 1.426 billion, the research states.
India is expected to have 1.668 billion people by the middle of the century, much above China's 1.317 billion, which would make it the most populated country in the world by 2023.
According to the analysis, between 2010 and 2021, eight nations saw a net outflow of more than 1 million migrants.
These outflows were often brought on by transient labor migrations, as was the case in Pakistan (net outflow of 16.5 million from 2010 to 2021), India (-3.5 million), Bangladesh (-2.9 million), Nepal (-1.6 million), and Sri Lanka (-3.5 million) (-1 million).
Conflicts and insecurity have led to a net outflow of migrants in other nations, such as the Syrian Arab Republic (-4.6 million), Venezuela (Bolivarian Republic of), and Myanmar (-1 million), over the past ten years.
In 2019, the average life expectancy at birth was 72.8 years, an increase of about 9 years since 1990. It is anticipated that further mortality declines would lead to an average worldwide lifetime of around 77.2 years in 2050.
But in 2021, the least developed nations' life expectancy lagged seven years behind the average worldwide.
The Institute of Health Metrics and Evaluation has also conducted other long-term population estimates (IHME).
IHME recently predicted that, with a range of 6.8 to 8.8 billion people, the world's population will reach 8.8 billion in 2100.
