Lifetime internal migration trajectories and social networks: Do repeat migrants fare worst?

While the economic benefits of internal migration are widely documented, the social costs of internal migration have received comparatively less attention. In addition, most studies focus on the impact of the last-recorded migration, ignoring the cumulative impact of successive migrations. Grounded in the life-course trajectory approach to migration and the convoy model of social networks, this paper addresses this gap by applying sequence and cluster analysis to retrospective data from the Survey of Health, Ageing and Retirement in Europe (SHARE) in 26 European countries to establish internal migration trajectories based on the timing, frequency, and direction of migration between NUTS-2 regions. The results reveal that differences in social networks between lifetime stayers, childhood migrants and one-time adult migrants are minimal. A more complex picture emerges for repeat migrants who account for half migrants and are split between return migrants, serial onward migrants, and circular migrants. Regression results show that repeat migrants – whether onward, return, or circular – display social networks less focused on family and more geographically dispersed, which results in a lower frequency of contact than lifetime stayers. However, repeat migrants report the same level of overall satisfaction with their social networks as lifetime stayers, which suggests that they start with different expectations than stayers or simply adjust their expectations in response to the social costs and benefits of migration. • Migrating once over the life course has a limited effect on an individual's social networks compared to lifetime stayers. • The impact of past migrations on social networks diminishes over time, particularly if migrations occurred early in life. • Repeat migrants have more geographically dispersed and less family-focused social networks compared to lifetime stayers. • Circular migrants report the most dispersed network and the lowest frequency of contact among repeat migrants. • Integration of the convoy model from social networks literature with the life-course trajectory approach from migration literature.
