The role of mobile internet access in evolving digital lifestyles is the cornerstone of the second typology of information and communication technology (ICT) users developed by the Pew Research Center’s Internet & American Life Project.  The typology places ICT users into 10 groups and, notwithstanding variation across the groups, the groups fit into two baskets, with the groups’ collective judgments on mobility being the pivot point.

This table summarizes how the groups use ICTs and group members' attitudes about them.
