Kilroy average age in 1911
The average Kilroy in 1911 was 31.6 years old, 32.5 for men and 30.7 for women; slightly older than the national averages of 29.6 for men and 30.5 for women. That low figure reflects just how many children there were in Edwardian Ireland, along with high infant mortality and the limits of public health at the time. For comparison, average life expectancy in Ireland today is around 83.
