This paper compares generations (G1, G1.5, G2, G3) of male Turkish migrants to Europe in their transnational behaviours: contact frequency, visits, remittances, property ownership and voting. We aim to explain differences by generational differences in transnational convoy size and integration into residence countries. Data from 798 members of migrant families were obtained from 2000 Families. Generations differ in visiting, remitting, property ownership and voting, but not in contact frequency. Using regression analysis, the transnational convoy cannot explain transnational behaviours. Structural and socio-cultural integration impact various transnational behaviours within generations. Generally, waning of transnational ties across generations cannot be attributed to differences in transnational ties or integration. We add to knowledge on generational differences in transnational behaviour until the third generation and on determinants of transnational behaviour, but conclude that the field of transnational studies is in need of further refinement of operationalization and theory to understand generational differences in transnational behaviour.
