medellivängd

Medellivängd is a Swedish term that translates to "life expectancy at midlife" or more literally, "midlife length of life." It refers to the average number of additional years a person is expected to live, given that they have already reached a certain age, typically around the middle of their life. This concept is distinct from overall life expectancy, which calculates the average number of years a newborn can expect to live. Medellivängd takes into account that individuals who have survived to a certain age have already overcome certain mortality risks.

This metric is often used by actuaries and demographers to understand mortality trends and predict future population health. For example, if a person has reached age 50, their medellivängd at 50 would be the average number of years they are expected to live from that point onwards. This figure is usually higher than the life expectancy at birth for the same population. Factors influencing medellivängd include lifestyle, health behaviors, access to healthcare, and socioeconomic conditions, all of which can impact survival rates in later life. Changes in medellivängd over time can indicate improvements or deteriorations in public health and healthcare systems.
