This document summarizes key findings about digital divides in the United States: 1) There remain divides in internet access and broadband adoption based on factors like age, income, education level, ethnicity, disability status, and whether people live in urban, suburban, or rural areas. 2) While home broadband adoption has increased overall, smartphone ownership has grown significantly and additional people now have internet access through smartphones even if they lack home broadband. 3) The main barriers for those who do not use the internet include lack of interest, not having a computer or access, difficulty using the technology, and not seeing its relevance to them.
