This article discusses the heterogeneity in children’s appropriation and use of the internet that make up contemporary digital divides. Based on a survey of Portuguese children in mandatory education (8- to 17-year-olds), it relies on multivariate statistical procedures to build a topological mapping of internet use patterns. Variations in digital practices and parental mediation are analysed in relation to social backgrounds and demographic traits. Four clusters of users were thus identified: ‘self-reliant cybernauts’, ‘nurtured cybernauts’, ‘nurtured beginners’ and ‘unguided rookies’. This article aims to contribute to deepening the debate on digital divides and digital diversity within the sociology of childhood.
