Generally speaking, older teens (those 14-17), are more likely to share certain types of information online than younger teens, ages 12-13. Older teens more frequently share a photo of themselves, their school name, their relationship status, and their cell phone number. While boys and girls generally share personal information on social media profiles at the same rates, cell phone numbers are the sole exception. Boys are significantly more likely to share their cell phone numbers than girls, a difference that is driven by older boys. Various differences between white and African-American social media-using teens are also significant, with the most notable being the lesser tendency for African-American teens to disclose their real names on a social media profile.
