Transnationalism as a concept serves as an analytical tool to grasp and differentiate a wide range of phenomena classified as transnational—that is, social, economic, political, and cultural processes that extend beyond the boundaries of nation-states. Transnationalism understood as a descriptive term refers to those same processes (i.e., conceptualizes as transnationalism the social, economic, political, and cultural processes) that transnationalism as a conceptual term seeks to understand and differentiate. In this entry, transnationalism is understood as a conceptual construct to refer to and account for transnational phenomena such as transnational interactions, identities, communities, and the like.
