I was looking at Swedish vital data from Statistics Sweden as a reaction to certain statistics floating around in the shadow of the ongoing covid-19 pandemic, when I accidentally happened to look at the age-specific sex ratio (males to females) in Sweden 2018, see Figure 1.
This is quite as expected, with the exception of the small peak at age 19. At age 61 women begin to dominate, which depends on the lower mortality among women.
Age-specific mortality by sex
Let us look at mortality by age and sex, more specifically the age-specific relative mortality of men compared to women, Figure 2.
The very erratic nature of the curve in the lower ages is of course due to the fact that mortality is very low in the early ages. More interesting is to notice that the female advantage seems to slowly diminish as the very high ages are reached. See Figure 3.
