Within the next seven years, India is predicted to overtake China as the world’s most populated country. By 2050 the world’s population is expected to reach 9.8 billion.
There will be 1.4 billion individuals aged 60 and above by 2030, potentially increasing to 3.1 billion by 2100.
Fertility declines due to an aging population and women in more industrialized nations not having the replacement rate of 2.1 children per woman. A country’s population declines if its fertility rate is lower than its replacement rate. As of 2015, the global fertility rate was 2.5. However, it was progressively dropping.
The United States will no longer be the world’s third-largest country. Instead, Nigeria will assume this place with 411 million people.
The Current Situation of Population
With a population of 1.41 billion people, China is now the world’s most populated country. However, by 2024, India and China are expected to have a population of 1.44 billion apiece. Following that, India’s population will continue to expand, while China’s Population will remain steady until the 2030s, when it begins to drop.
The Growth Rate is High in Africa
In 2050, Africa will have three of the top ten most populated countries. The world’s seventh most populated country, Nigeria, will ascend to third by 2050.
Ethiopia and DR Congo will replace Russia and Mexico as the ninth and tenth most populated countries.
According to the research, many African nations will rise in the ranks during the next three decades due to high fertility rates and higher life expectancy. As a result, populations in 40 countries, mainly in Africa, are expected to double, according to the figures.
1. India (2050: 1.66 Billion)
India’s population is expected to reach 1.66 billion people by 2050. However, according to government data, the Total Fertility Rate in India has already achieved replacement levels.
By 2030, India’s population will have risen to 1.5 billion. At the moment, India has 16% of the world’s population but just 2.45% of the global surface area and 4% of the world’s water resources.
On January 20, 2020, the Supreme Court of India issued a notice to the Union government, requesting strict legislation to regulate the population.
Muslims are predicted to increase faster than Hindus since they have the youngest median age and the greatest reproductive rates among India’s major religious groups.
Even with this rise, Hindus will account for more than three-quarters of Indians (76.7 percent) by 2050. Indeed, the number of Hindus in India will still be more than the five greatest Muslim populations in the world’s major Muslim countries (India, Pakistan, Indonesia, Nigeria, and Bangladesh combined).
2. China (2050: 1.36 Billion)
In 2050, China’s population is predicted to fall to 1.36 billion. After reaching a peak of 1.44 billion in 2029, China’s Population, the world’s biggest, is expected to see continual negative growth beginning in 2030.
The average number of children a woman will have is 1.6. And negative population growth is expected in 2027, with a probable total population of 1.17 billion, equal to 1990.
3. Nigeria (2050: 410.64 Million)
Nigeria’s population was predicted to be about 216.7 million in 2022. The people of Nigeria are anticipated to more than double by 2050.
Nigeria’s population is mainly growing due to the first component, a high birth rate. The enhancement of medical treatment contributes to population growth. For example, vaccines are available in modern medicine to assist adults and infants recover from illness and living longer lives.
Between 1965 and 2022, the Population of Nigeria expanded at a pace of more than 2% every year. In 2021, the population increased by 2.6 percent over the previous year. Nigeria is Africa’s most populous country. As a result, the African continent has the world’s greatest growth rate.
With Nigeria’s Population expanding at more than 3% per year, Nigerian officials attempt to halt population growth by providing accessible family planning tools and guidance to Nigerian households.
4. USA (2050:389.59 Million)
The Population of the United States in 2021 is expected to be about 331.89 million people. New York Metropolis is the most populous and densely inhabited city in the United States. Around 16.5 percent of the American Population was 65 or older, predicted to rise to 22 percent by 2050. In recent years, the United States’ aging population has been highlighted as a source of concern since the nature of labor and retirement is expected to alter to keep up.
If a population is predicted to live longer than previous generations, the economy must adapt to meet the residents’ requirements. Furthermore, the birth rate in the United States has been declining over the last 20 years, implying fewer young people to replace those leaving the workforce.
5. Indonesia (2050: 321.55 Million)
Rice output in Indonesia has steadily expanded over the last several decades. However, the rise in food consumption outpaces the increase in production. As a result, Indonesia’s population is expected to expand by 24.5 percent over the next four decades.
By 2030, Indonesia will contribute to approximately 40% of ASEAN growth. A young population—nearly 60% is under 30 years old—and a population growing at a pace of 2.9 million per year are critical growth drivers.
In 2022, Indonesia’s population will be 278,578,611. The Population of Indonesia is comparable to 3.51 percent of the total world population. 56.4 percent of the population lives in cities.
6. Pakistan (2050: 306.94 Million)
Pakistan’s population will exceed 380 million by 2050. At Pakistan’s current growth rate of 3.6 percent, the number of people would double in 19.4 years.
7. Brazil (2050: 232.69 Million)
In various ways, the rising number of Brazilian women entering the labor force and electing to postpone having children is impeding the country’s growth.
Brazil’s birth rate has declined dramatically since the 1970s when women had an average of more than four children. The current birth rate is 1.77 per woman, lower than the US average. However, this rate is expected to decline to 1.5 by 2034 and remain there until 2060.
8. Bangladesh (2050: 201.93 Million)
Bangladesh has a current population of 167,498,145 people as of April 3, 2022. Bangladesh’s population is expected to reach 179.00 million in 2030, climb to 192.57 million in 2050, and decline to 151.39 million by 2100. Bangladesh is home to 2.1 percent of the world’s population. However, its worldwide share would fall by 2.0 percent in 2040 and is expected to fall to 1.4 percent by 2100.
Bangladesh’s population is rapidly growing. Bangladesh’s population is growing at 22 percent (per thousand). Therefore, Bangladesh’s population crisis is the country’s most pressing issue.
9. Democratic Republic of Congo (2050:197.40 Million)
The country has 89.6 million people, a 3% annual population growth rate, and 46% of the population under 15. The Current Population is 94,315,871. The population density of the Democratic Republic of the Congo is 40 people per square kilometer. Therefore, 45.6 percent of the population lives in cities.
The age structure of the DRC’s population pyramids is not expected to alter significantly until between 2030 and 2050. The Democratic Republic of the Congo’s median age is 17.0 years.
10. Ethiopia (2050: 190.87 Million)
Ethiopia now has a population of little more than 110 million people, evenly divided between males and females. Around 70 million people are under 29, and 45 million are under 24. The problems of having such a youthful populace would have decimated the country if not because 80% of the population now lives in rural regions.
With a population growth rate of 3.8 percent each year, Ethiopia’s overall population will reach 202.5 million by 2050. The existing urban population (less than 20%) is expected to more than treble to 60 million by 2050.
After 2050, the world’s population is predicted to fall, with 183 of the 195 nations failing to meet the replacement threshold required to sustain population levels. Liberal immigration policy might aid in the preservation of population and economic growth.
