Ageing societies are facing challenges from the perspective of the use of information and communication technologies (ICTs). There is an increase in online services relevant for the economic, political, cultural and private life. Those who participate more fully in a digitally mediated social life enjoy advantages over their digitally disadvantaged counterparts. Today’s digital divide is not first and foremost between pensioners and others, but between younger and older pensioners. Scholars identify the need for longitudinal research among younger and older seniors to understand the differences between more or less advantaged users. Based on longitudinal, representative surveys, the present study finds that there is a clear gap between younger and older seniors, and that it is closing only very slowly. Age and level of education are powerful explanatory factors whereas generational belonging and social capital contribute only to a limited extent to the understanding of Internet uptake among older adults.
