Counties with Mahon in Ireland
Dublin had the largest share of Mahons, 18.6% (683 people). Next came Galway (405), Roscommon (319), Offaly (275) and Leitrim (270).
Mahon average age in 1911
The average Mahon in 1911 was 30.8 years old, 30.4 for men and 31.2 for women; almost exactly in line with 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.
Mahon literacy in 1911
Of the Mahons whose literacy was recorded, 76.4% could both read and write, 4.2% could read but not write, and 19.4% could do neither. The figures were much the same for men and women. Bear in mind these figures include young children; the census itself only counted people aged nine and over when calculating illiteracy, on the grounds that it was unfair to label a child illiterate before they'd had a chance to learn.
