Translation of "voluntary migration" into Chinese

With most people moving for a variety of reasons, it is difficult to make a strict distinction between voluntary migration and forced displacement.

由于大多数人移徙的原因各不相同,因此很难严格区分自愿移徙和被迫流离失所。

Indeed, the “migration-asylum nexus” reflected that it was sometimes difficult to distinguish between forced and voluntary migration

实际上,与移民和避难密不可分的一些问题表明,有时很难区别被迫移民与自愿移民。
