Weltbevölkerung

Weltbevölkerung refers to the total number of humans currently living on Earth. This number is not static, but constantly changing due to births and deaths. Estimates of the world population are compiled by various organizations, including the United Nations and the U.S. Census Bureau.

Throughout history, the human population has grown exponentially, particularly in recent centuries. Factors contributing to this growth include advances in agriculture, sanitation, medicine, and a general increase in life expectancy. However, the rate of growth has begun to slow in many parts of the world.

Understanding world population trends is crucial for addressing global challenges such as resource allocation, environmental sustainability, economic development, and social planning. Different regions of the world have varying population densities and growth rates, influenced by factors like fertility rates, mortality rates, and migration. Demographers analyze these patterns to project future population figures and their potential impacts. The concept of carrying capacity, the maximum population size that an environment can sustain indefinitely, is also a related area of study in relation to world population.
