Why do people migrate?

By Paul Andrew Bourne

Introduction

According to Goldsheider (1998) migration is the "detachment from the organization of activities at one place and the movement of the total round of activities to another." That is, people who move from one place to another while changing their usual place of residence are migrants. This definition, however, excludes people who move from one place to another without changing their place(s) of abode. For instance, vacation travelers and people whose jobs necessitate traveling from one place to another.

The categories most frequently used in the studies of migration distinguish between moves across international boundaries, (that are from one county to another international migration) and move between different places in the same country (that is internal migration). For example, a person who comes from Barbados to live in Jamaica here is called an immigrant. On the other hand, a person who leaves Jamaica to reside in Barbados is called an emigrant. Previously, those situations are within the scope of international migration (that of, emigration and immigration), whereas, internal migration speaks specifically to the changing of ones place of abode within the same the same geographically defined border. A typical example is an individual who removes from Southside, Kingston (irrespective of specificity of address) to reside permanently in Flanker, Montego Bay, St. James or from Caroni to St. Patrick in the twin islands of Trinidad and Tobago.

A component in the population dynamics of any country is external migration. However, both internal and external migrations are important components of population change. External migration has been a major contributor to the reduction in population growth. Jamaica and Trinidad and Tobago are affected by internal migration in terms of the predominant rural to urban drift. External migration or the permanent change of residence from the country to another affects the population redistribution and change. Geographic mobility has played a major role in the distribution and redistribution of humans on the surface of this planet.

Both internal and external movements are largely influenced by imbalance in the development process and associated push and pull factors. The process of immigration and emigration influences migration rate. Immigrants to Jamaica and the twin islands of Trinidad and Tobago may include returning residents, deportees, Commonwealth citizens and aliens. Both processes have affected these countries' population structure.
