Clare was Leyden country: 44.4% of them (190 people) lived there in 1911. Next came Sligo (124), Derry (20), Leitrim (18) and Roscommon (18).

Leyden average age in 1911
The average Leyden in 1911 was 29.6 years old, 30.2 for men and 29.1 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.

Men came out slightly ahead, 80.8% reading and writing against 72.4% of 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.
