Transnationalism Survey Measurement

Transnationalism survey measurement is the set of techniques for turning the slippery idea of immigrant transnationalism — living life across borders — into countable survey data. Alejandro Portes and his collaborators, working through the Comparative Immigrant Entrepreneurship Project (CIEP) and related studies, argued that transnationalism should be reserved for activities that require regular, sustained cross-border involvement, not the occasional phone call or holiday visit that virtually every immigrant makes. Their 1999 programmatic statement with Guarnizo and Landolt laid out the pitfalls of a concept stretched to cover everything, and Portes's 2003 synthesis distilled the empirical lessons into a measurement strategy. The method asks respondents about specific economic, political, and sociocultural cross-border activities, records how often each is performed, and uses an intensity threshold to separate genuinely transnational individuals from the merely connected. From these items the analyst builds a typology by domain and intensity and then estimates how common transnationalism is and who practices it. The result disciplines a fashionable but vague concept into a measurable, comparable construct.
