Elinikäarvion

Elinikäarvion, a Finnish term that translates to "life expectancy estimate," is a statistical calculation used to predict the average number of years a person or a group of people is likely to live. This estimate is derived from various demographic and health-related data, including mortality rates, age structure, and disease prevalence within a population.

Life expectancy is not a prediction of how long any single individual will live, but rather an average for a given cohort. Factors influencing life expectancy estimates include socioeconomic status, access to healthcare, lifestyle choices, environmental conditions, and public health initiatives. Different methodologies exist for calculating life expectancy, with the most common being period life expectancy and cohort life expectancy. Period life expectancy calculates the average lifespan based on current mortality rates, while cohort life expectancy considers how mortality rates might change over an individual's lifetime.

Globally, life expectancy has seen a significant increase over the past century due to advancements in medicine, sanitation, and nutrition. However, disparities persist between countries and within populations, highlighting the impact of social and economic determinants on health. Elinikäarvion serves as a crucial metric for public health planning, policy-making, and understanding the overall well-being and development of a society. It is also used in fields like insurance and retirement planning.
