Of the McGuinesses whose literacy was recorded, 76.3% could both read and write, 6.1% could read but not write, and 17.5% could do neither. Women came out slightly ahead, 78.9% reading and writing against 73.7% 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.
