Abstract
At older ages, the average and the standard deviation of remaining lifetime (ARL and SRL) are both less than at younger ages. us ARL and SRL change together. A linear relationship of slope 1 between the reciprocals of ARL and SRL has previously been found. e present paper reports similar relationships when considering different countries, years, and sexes. It is suggested that age and sex of person, their country, and the year all act via the same unobserved variable, that might be called effective age.
