Elinikäarvossa, also known as life expectancy, is a statistical measure of the average age at which members of a particular population are expected to die. It is commonly used as an indicator of the health and well-being of a population. Life expectancy at birth is the most commonly reported measure, representing the average number of years a newborn infant can expect to live if current age-specific mortality rates remain constant throughout their life.

Life expectancy can vary significantly between different countries, regions, and even within the same country over time. Factors influencing life expectancy include access to healthcare, nutrition, sanitation, and overall living conditions. Improvements in these areas generally lead to increases in life expectancy.

Life expectancy is typically calculated using mortality data from national vital statistics systems. It can be broken down into different categories, such as male and female life expectancy, and can be further subdivided by age groups or specific causes of death. For example, infant mortality rate, which measures the number of deaths of infants under one year old per 1,000 live births, is a critical component of overall life expectancy.

In recent decades, global life expectancy has been increasing due to advancements in medicine, public health initiatives, and economic development. However, disparities remain, with some regions experiencing higher life expectancy than others. Monitoring life expectancy is essential for tracking progress in public health and identifying areas where further improvements are needed.
