The Millars were heavily concentrated in Antrim, home to 53.8% of them (1,973 people). Next came Down (524), Derry (384), Tyrone (184) and Donegal (116).

Millar average age in 1911
The average Millar in 1911 was 28.2 years old, 27.8 for men and 28.6 for women; a touch younger 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.

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.
