According to a new UN report released on Thursday, the world’s population is predicted to increase by more than 2 billion people over the next several decades, reaching a peak of roughly 10.3 billion in the 2080s—a significant change from a decade ago.
Reliable population data is more crucial than ever because of the uneven changes in the world’s population and the changing demographic landscape, which includes rapid population growth in some regions and rapid ageing in others, according to the United Nations Population Fund (UNFPA).
In 2024, the population of 63 countries and regions peaked, including China, Germany, Japan, and the Russian Federation. Over the next 30 years, it is predicted that the overall population of this group will decrease by 14%.
The population of the remaining 48 nations and regions—including Brazil, Iran, Turkey, and Vietnam—is expected to peak between 2025 and 2054. The population of the remaining 126 nations, which include the US, India, Indonesia, Nigeria, Pakistan, and Indonesia, is predicted to grow through 2054 and may peak later in the century.
Angola, the Central African Republic, the Democratic Republic of the Congo, Niger, and Somalia are among the nine nations in this final group that are expected to experience extremely rapid growth, with a doubling of their total population between 2024 and 2054.
