Levnadshalvår

Levnadshalvår is a Swedish term that translates to "lifetime half-year" or "life half-year." It is a measure used in public health and actuarial science to quantify the remaining life expectancy from a specific point in time, typically at birth. Instead of expressing life expectancy as a single number of years, levnadshalvår considers the remaining life expectancy in discrete six-month periods. This approach allows for a more granular understanding of survival probabilities at different ages.

The concept is particularly relevant in contexts where statistics on life expectancy are presented or analyzed. For example, if the life expectancy at birth is stated as 40 levnadshalvår, it means that an individual is expected to live for an additional 40 periods of six months, totaling 20 years. This unit of measurement helps to avoid rounding issues and can be useful for comparing life expectancies across different populations or time periods with greater precision. It is a statistical construct designed to refine the presentation of demographic data related to longevity.
