- Abstract:
- This paper studies how increasing migration changes the character of migrant streams in sending communities. Cumulative causation theory posits that past mi- gration patterns determine future flows, as prior migrants provide resources, influence, or normative pressures that make individuals more likely to migrate. The theory implies uniform patterns of exponentially increasing migration flows that are decreasingly selective. Recent research identifies heterogeneity in the cumulative patterns and selectivity of migration in communities. We propose that this heterogeneity may be ex- plained by the differential accessibility of previously accumulated migration experience. Multi-level, longitudinal migration data from 22 rural Thai communities allow us to measure the distribution of past experience as a proxy for its accessibility to community members. We find that migration becomes a less-selective process as migration expe- rience accumulates, and migrants become increasingly diverse in socio-demographic characteristics. Yet, selectivity within migrant streams persists if migration experience is not uniformly distributed among, and hence not equally accessible to, all community members. The results confirm that the accumulation and distribution of prior mi- grants' experiences distinctly shape future migration flows, and may lead to diverging cumulative patterns in communities over time.
