Summary
The world population will reach 8.09 billion on New Year’s Day 2025, growing by 71 million people (0.9%) in 2024, according to U.S. Census Bureau estimates.
This marks a slight slowdown from 2023’s 75 million increase. Globally, 4.2 births and 2.0 deaths are expected every second in January 2025.
Eventually, climate change will cause a drop in population, but not before causing catastrophic environmental changes that lead to increased food scarcity.
