Data from the UN’s December 2022 population estimates, along with summaries from the French Institute for Demographic Studies, has helped in visualising the changing world population by country below.
Around the world, 250 children are born per minute on average. This amounts to more than 130 million new individuals being born each year.
The world’s population has more than tripled since the middle of the 20th century, reaching a staggering 8 billion people.
In order to depict the uneven growth and decline of the global population by 2050, Truman Du used data from the UN’s December 2022 population estimates along with summaries from the French Institute for Demographic Studies (INED).
Most Populous Countries: 2022 vs. 2050
For hundreds of years, the Asian nations of China and India have ranked first and second, respectively, in terms of population.

At the moment, China is ranked first on this ranking. But by the end of this year, India’s population is anticipated to surpass China’s, rising to a total of 1.67 billion in 2050.
In terms of population, the United States, Nigeria, Pakistan, and Indonesia will likely remain in those positions through 2050. They still have a long way to go before overtaking the top two, as their combined population isn’t even close to what India and China have in number.
Intriguingly, it is predicted that by 2050, Nigeria’s population would surge to 375 million, nearly eclipsing that of the United States. The African nation had just about 219 million people as of 2022. This anticipated increase is mostly the result of a high birth rate, a flourishing economy, and the subsequent migration from rural to urban areas.
Countries with Declining Populations
Over the next three decades, the population of many countries will increase, although China is predicted to suffer the opposite.
Over the next 30 years, population decline is anticipated in a number of nations. And the fundamental cause of this is the shockingly low birth rate.
The population of South Korea, which has the lowest fertility rate in the world, is predicted to drop sharply by about 12% by 2050, reaching 46 million.
Global economies may face difficulties as a result of these population trends, which include labour shortages, ageing populations, and an increased financial load on younger generations.
