The human population refers to the total number of people living on Earth at any given time. As of October 2023, the global population is estimated to be over 8 billion. This population is distributed unevenly across different regions, with areas like Asia and Africa experiencing the highest growth rates, while some countries in Europe are seeing population declines. Population growth is influenced by various factors, including birth rates, death rates, and migration patterns. Urbanization, advancements in healthcare, and improved living conditions have contributed to increased life expectancy. Understanding human population dynamics is essential for addressing challenges such as resource management, environmental sustainability, and social services.
