The YouTube audience is large and diverse: Includes all the family: 14-17 year olds only make up 7% of Australian YouTube users (18-29 = 32%, 30-39 = 20%, 40-49 = 18%, 50-59 = 13% and 60+ = 10%). Are workers, students, stay-at-home mums and retirees: 57% are working, 19% are stay at home, and only 15% are studying. Encompasses all life stages: 55% are married, 35% are single and 9% are divorced. Are not just techies and nerds: 61% of YouTube users are not tech-savvy.
