In the first full-length scholarly study of the increasingly important phenomenon of digital diasporas, Jennifer M. Brinkerhoff examines how immigrants who still feel a connection to their country of origin use the Internet. She argues that digital diasporas can ease security concerns in both the homeland and the host society, improve diaspora members' quality of life in the host society, and contribute to socio-economic development in the homeland. Drawing on case studies of nine digital diaspora organizations, Brinkerhoff's research supplies new empirical material regarding digital diasporas and their potential security and development impacts. She also explores their impact on identity negotiation, arguing that digital diasporas create communities and organizations that represent hybrid identities and encourage solidarity, identity, and material benefits among their members. The book also explores these communities' implications for policy and practice.
