Counties with Jeffrey in Ireland
The Jeffreys were heavily concentrated in Down, home to 50.3% of them (77 people). Next came Antrim (41), Dublin (10), Tyrone (8) and Derry (6).
Jeffrey average age in 1911
The average Jeffrey in 1911 was 29.0 years old, 27.5 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.

Women came out slightly ahead, 96.1% reading and writing against 93.9% of men. 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.
