The usage of "they" in the singular number is a pretty new concept. Although there's evidence that it was used well over a 100 years ago, the popularity of the singular they started only some 30, 20 years ago. Before that, constructions like "he/she", "(s)he" were used, or even the generic he (using masculine pronouns to refer to persons regardless of gender). In recent times, the singular they has become so popular that language and style guides include it as valid English. I could babble on about English linguistics still for a good while, but I think I'll end it here.
