Breen in 1911 Ireland
The 1911 Census recorded 4,509 people named Breen in Ireland, about 0.103% of everyone living in the country at the time and the 179th most common surname overall. The name was split fairly evenly between men and women: 2,246 men and 2,258 women. (A small number, 5, had no sex recorded.)
Counties with Breen in Ireland
Wexford had the largest share of Breens, 17.5% (791 people). Next came Kerry (624), Dublin (442), Tipperary (310) and Fermanagh (295).

Breen average age in 1911
The average Breen in 1911 was 30.2 years old, 30.0 for men and 30.3 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.
Breen literacy in 1911
Of the Breens whose literacy was recorded, 77.2% could both read and write, 3.8% could read but not write, and 18.9% 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.
Breen common first names
