Introduction
Migration is the movement of individuals or communities from their settlements of origin across borders or within the state in which they live. In migratory population movements, individuals are displaced for various yet significant amounts of time, through the involvement of different structural factors, and for different reasons.2 People migrate from one place to another, either compulsorily or voluntarily, for reasons such as war, epidemics, natural disasters, economic problems, or the search for better living conditions, jobs, or educational opportunities. It can be modern or primitive, forced or free, small-scale or massive.3
