Global Population to Peak at 10.3 Billion by 2080, Then Decline

A UN report projects the world population will peak at 10.8 billion in the 2080s before declining to 10.2 billion by 2100, driven by factors like urbanization and migration but tempered by falling fertility rates. Over half of countries have fertility rates below the replacement level, with some experiencing "ultra-low" rates. This demographic shift could reduce environmental pressures due to lower consumption. Peak population has already occurred in 63 countries, while others will reach it between 2025 and 2054. The US and 125 other countries are expected to continue growing until the latter half of the century.
