After the global population hit eight billion on 15 November 2022, various predictions have been made about when the number of people on Earth will peak. Studies vary, with some suggesting that world population will peak at 8.8 billion people by the middle of this century, before it starts to decline. Other predictions, such as those made by the United Nations, estimate that the world’s population could hit more than 10 billion by the 2080s.

To put this list into some kind of perspective, the population of Greater London, UK, is about nine billion, and New York, USA, is approximately 8.5 billion.
