world population
Earth's human total
World population is the total number of human beings alive on Earth at a given time.
The figure serves as a baseline for discussions of demographics, resource consumption, and environmental impact: World population reached eight billion in 2022.
The phrase often carries undertones of concern about growth rates and sustainability.
