According to this study referenced by Wikipedia [1] ("Why Men Die Younger: Causes of Mortality Differences by Sex" [2]):
>In her extensive review of the existing literature, Kalben concluded that the fact that women live longer than men was observed at least as far back as 1750 and that, with relatively equal treatment, today males in all parts of the world experience greater mortality than females.
A counterpoint to the point made on higher war related male mortality in the past is that mortality rates for females in child-bearing age groups have traditionally been higher than men of the same age, although this is no longer the case. [1]
