The target sample for this study was mobile users aged 13 to 18. Proportions range from only 2.7% who were 13 years of age to more than one-third of the sample (35.5%) who were 18 years old. Overall, three out of four respondents in this study were between the ages of 16 and 18.

The age distribution of this sample is presented in Figure 1.

Additionally, 56% of the sample were male, and 44% were female (not shown). As shown in Figure 2, females represented a slightly larger proportion of respondents among 14-, 16-, and 18-year-olds; males, on the other hand, were more prevalent among 13- and 17-year-olds.
