The 1911 Census recorded 170 people named O'Hea in Ireland; roughly one in every 26,000 people carried the name. The name was split fairly evenly between men and women: 87 men and 82 women. (A small number, 1, had no sex recorded.)
Counties with O'Hea in Ireland
The O'Heas were heavily concentrated in Cork, home to 76.5% of them (130 people). Next came Derry (10), Dublin (10), Meath (8) and Limerick (5).
O'Hea average age in 1911
The average O'Hea in 1911 was 29.5 years old, 28.5 for men and 30.6 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.
O'Hea literacy in 1911
Of the O'Heas whose literacy was recorded, 87% could both read and write, 2.4% could read but not write, and 10.7% could do neither. Women came out slightly ahead, 89% reading and writing against 84.9% 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.
