[The Tamil migratory cycle, 1830-1950].
The author examines international migration from the Indian State of Tamil Nadu during the period 1830-1950. "An attempt is made to interpret migration processes in terms of [the] migratory cycle. The cycle of migration streams is divided into three phases: perfect regulation, growing independence, government-controlled termination. These stages of the cycle correspond to the progressive constitution of a permanent migrant community in receiving countries. Such a pattern can help analyse other examples of international labour migration in the contemporary situation." (SUMMARY IN ENG AND SPA)
