Two decades have passed since seminal work on the dimensions of digital inequality (DI) appeared. Since that time, digital inequalities have grown and taken on different forms. However, the research on conceptualizing and measuring DI has not progressed significantly. Particularly, there is a lack of robust theories to tackle the growing societal problem of DI, which is closely linked to a complex set of individual and institutional factors. Along these lines, by following a five-stage scoping review process, the current landscape of DI is mapped in this work. In addition, the key factors influencing DI are identified. As a result, a robust base for the development of a conceptual framework for further DI research is provided. The proposed framework can be validated empirically and also used to investigate the DI phenomenon in various contexts and levels.
