Of the McDarbys whose literacy was recorded, 78.3% could both read and write, 3.6% could read but not write, and 18.1% could do neither. Women came out slightly ahead, 86.4% reading and writing against 69.2% 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.
