In the context of primary education, students aged 11-12 years old begin to integrate digital devices and online behaviours that are more common and widespread at the secondary level. The objective of this study is to understand the factors that determine the initial digital ecosystem of students, and to evaluate the risks that these students face at a certain threshold age. The 356 participants in the sample completed a questionnaire designed ad hoc based on the findings of other studies with the same aim. The identified correlations and the regression equations obtained indicate, fundamentally, that two out of every three students who own a smartphone use it to communicate with family and friends. Furthermore, the use of mobile phones encourages young people to join and participate in social networks at an early age. The study also reveals that at this age, students use social networks mainly for the consumption of audiovisual content and not so much to share personal information of a critical nature. Finally, students in this particular age group are considered at a threshold age because they begin using smartphones regularly, making autonomous decisions without sufficient supervision regarding digital risks, thus becoming part of the Frontier Collective.
