McCay average age in 1911
The average McCay in 1911 was 33.8 years old, 34.6 for men and 33.2 for women; noticeably 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.
