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. (Contains 1 figure, 4 tables, and 15 notes.)
