This study deals with the statistic results acquired for life expectancy of the male population in Noricum. They were compared with the data from other Danubian provinces (Pannonia Superior, Pannonia Inferior, Dacia, Moesia Superior, Moesia Inferior) and from Roman Egypt. We stopped on the age-rounding process, analysing the rapport between rounded ages and unrounded ages at the level of the entire male sample. For an insight of the male population we compared the age structure values from all the Danubian province on three age categories, in terms of numbers and percentage.
