Lebenserwartungsschätzung
Lebenserwartung, often translated as life expectancy, refers to the average number of years a person is expected to live. It is a statistical measure calculated based on current mortality rates across different age groups within a population. This figure is not a prediction for any individual but rather an indicator of the general health and living conditions of a society. Factors influencing life expectancy are diverse and include access to quality healthcare, nutrition, sanitation, lifestyle choices such as diet and exercise, environmental conditions, and socioeconomic status. Historically, life expectancy has increased significantly over time due to advancements in medicine, public health initiatives, and improved living standards. Variations in life expectancy exist not only between countries but also within populations, often correlating with gender, income level, and geographical location. It is a key metric used by demographers and public health officials to assess the well-being of a population and to guide policy decisions aimed at improving health outcomes. Understanding life expectancy helps in planning for social security, healthcare services, and long-term societal development.
