1. When will the world population reach 8 billion?
The day of 8 billion, which is when we say global population will reach 8 billion people, is November 15, 2022. This date is chosen by demographers at the United Nations and is a symbolic date. But spoiler: the reality is that no one knows exactly when we’ll reach exactly 8 billion people.
2. How do we know the world has 8 billion people?
The Statistics Division at the UN is responsible for collecting and tracking global population data. The data itself comes to the UN at the country level and is submitted by individual nations’ statistical offices. So a country counts its population, provides its population data to the United Nations, and the UN uses that data to determine the global population.
