Migration can be seen as a process in which large numbers of individuals and families begin to write a new history for themselves. The initial act of leaving one's parents, family, neighbourhood, society and culture, and adopting a new life- and work-style is a crucial one. Only a small proportion of people who enter a migration process, or who have participated in major migration movements in the past, have had a clear perception of what they were going to encounter, or the extent to which their lives were going to change. While it is very likely that a large proportion of the individual migrants are the forerunners in a migration which will ultimately involve other members of their kin network, they are not usually able to foresee this at the time.
