The world population is the total number of humans currently living on Earth, estimated to be around 8 billion as of late 2023. This number has grown exponentially, particularly in the last century, due to advancements in medicine, agriculture, and sanitation, leading to increased life expectancy and decreased mortality rates. While population growth continues globally, it is unevenly distributed, with some regions experiencing rapid growth while others face declining populations. Understanding the dynamics of world population is crucial for addressing global challenges such as resource management, environmental sustainability, and economic development.
