Roscommon had the largest share of Tiernans, 20.6% (219 people). Next came Leitrim (177), Dublin (100), Louth (93) and Mayo (90).
Tiernan average age in 1911
The average Tiernan in 1911 was 30.2 years old, 30.4 for men and 30.1 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.

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.
