According to the UnitedNations, the world population reached 8 billion people on 15 November 2022
It took only 12 years to add another 1 billion people to the total global population
The global population is growing at its slowest rate since 1950, falling under 1% in 2020
The latest projections by the United Nations suggest that the world's population could grow to around 8.5 billion in 2030 and 9 billion in 2048
The populations of 61countries or areas are projected to decrease by 1% or more between 2022 and 2050, owing to sustainedlowlevelsoffertility and, in some cases, elevatedratesofemigration
