An average of 250 babies are born every minute in the world, which is more than 130 million new people every year. No wonder the population, now a whopping 8 billion, has more than tripled since the mid-20th century.
Check out Visual Capitalist’s infographic, based on UN data for December 2022 and projections from the French Institute for Demographic Studies (INED), to show the difference in world population growth and decline by 2050.
Countries with the largest population: 2022 VS 2050
The Asian countries India and China have been leading the rankings of the world’s most populous countries for hundreds of years. China tops the list, but India is expected to overtake it by the end of 2023, eventually reaching 1.67 billion people in 2050.

The United States, Nigeria, Pakistan, and Indonesia are the next most populous countries in 2022 and are expected to hold these positions until 2050. However, these countries have a long way to go to overtake the top two leaders, as even their combined population is less than half of the total number of people living in India and China.
Nigeria’s population is estimated to grow to 375 million by 2050, almost comparable to that of the United States. In 2022, the population of the African country was only about 219 million. The expected increase in indicators is due to a high birth rate, a booming economy and, as a result, migration from rural areas to cities.
Countries with decreasing population
While many countries will see population growth over the next three decades, others such as China are expected to see the opposite.
The population of a number of countries around the world is expected to decline over the next 30 years. And the main reason for this: a very low birth rate.
South Korea, which has the world’s lowest birth rate, is expected to experience a dramatic population decline of nearly 12%, falling to 46 million by 2050.
Such a shift in global demographic trends could create challenges for economies around the world, such as labor shortages, aging populations, and increased financial burdens on younger generations.
