4 ‘Sexually diverse’ includes participants who identified their sexual orientation as 'gay or lesbian’, ‘bisexual’, ‘queer’, ‘asexual’, ‘pansexual’ or that they are ‘still working it out’. Sexuality was asked only of children aged 13–17.

5 12-month incidence for sexually diverse teens didn’t differ significantly to 12-month incidence for straight teens.

6 The smaller sample size for trans and gender-diverse children should be considered when interpreting these findings (n=83).

7 12-month incidence for trans and gender-diverse children didn’t differ significantly to 12-month incidence for girls or boys.

8 Arrows denote statistically significant differences between sub-groups. The proportion of children aged 13 to 15 and 16 to 17 who experienced non-consensual tracking, monitoring or harassment in the past 12 months didn’t differ significantly.
