Seasonal and Circular Migration

Not all migration is a one-way move. Circular migration describes people who move repeatedly between their home and one or more destinations, working away for part of the time and returning home in between. Seasonal migration is a common form of it, tied to the rhythm of harvests, construction seasons, or tourism. For many families around the world, especially in lower-income rural areas, moving back and forth is a normal part of earning a living.

Why people move in cycles

Circular migration often makes economic sense. Farming families may have little work between planting and harvest, so one or more members go to a city for construction, brick-making, or factory work during the slack season, then return when the farm needs hands. Others keep their families at home because housing in the city is expensive or schools and support networks are better in the village. In India, for example, millions of workers from states such as Bihar, Uttar Pradesh, and Odisha travel to cities or other states for part of the year. In China, the annual journey home of migrant workers for the Spring Festival is one of the largest regular movements of people on Earth.

Formal seasonal worker schemes

Some countries run temporary labor schemes that let workers come for a season and then return. New Zealand’s Recognised Seasonal Employer scheme and Australia’s Pacific labour programme bring workers from Pacific Island countries to pick fruit, prune vines, or work in meat processing. Similar programmes exist in Canada and parts of Europe. Studies of the New Zealand scheme have found meaningful income gains for participating households in places like Tonga and Vanuatu.

Benefits and trade-offs

Circular migration can offer many of the gains of migration while keeping families and communities connected. Workers earn higher wages, home communities receive income, and destination employers get labor when they need it most. Because workers return, some worries about permanent population change are reduced.

But there are real costs. Many circular migrants live in split households, with parents separated from children for months at a time. Temporary workers often have weaker legal protections, may be tied to one employer, and can face poor housing or long hours. Another challenge is portability, meaning whether benefits and rights travel with the worker. Migrants moving within India, for instance, have sometimes lost access to subsidized food, voting, or local services while away from their registered home, and circular migrants abroad may pay into pension systems they never benefit from.

Designing better systems

Researchers and international organizations suggest several improvements: making benefits portable, letting temporary workers change employers, enforcing housing and pay standards, and offering the option of longer stays for workers who want them. The goal is to keep the flexibility of circular migration while reducing the risks it places on workers.
