Life expectancy

In this news release, period life expectancy is meant. This was developed to still be able to make statements about life expectancy for current populations based on current data. It indicates how old people become on average if the mortality probabilities by age of that year were to apply throughout their lives. Mortality probabilities change every year, therefore period life expectancy can be interpreted mainly as a summary measure of mortality in a given year.
Period life expectancy is the number of years that a person of a selected age is expected to live under the assumption that the mortality rates on which the life table is based will not change in the future.
The period life table is a table showing how many out of 100 thousand newborns will reach the age of 0 to 1, 2 etc., based on the mortality ratios that have actually been observed over a certain period.
Mortality or death probability means the probability of death before reaching the next age. The probability is calculated as the observed number of deaths in the selected period per 100 thousand of the average (real) population of equal age and sex.
