The migration causes. A brief bibliographical review

Abstract

The migratory phenomenon has been a constant since the beginning of history and, in recent years, it
has increased both in developed and developing countries, and which origin is due to different reasons.
Therefore, its analysis becomes necessary for the understanding and control of the subject in question.
This is the reason why,the objective of this research was to identify and describe the most frequent reasons
that motivate migration, according to the available literature. To achieve this, an in-depth bibliographic
review was carried out, through the analytical-synthetic method, during the period 1982-2022. The selection of the theoretical material used was carried out through a signing process, following the inductive-deductive method. The results indicated that there are at least five main categories that promote migration, these being economic, social, political, demographic and ecological, each with its own particular motivations. It was concluded that the migratory phenomenon does not arise within a specific temporality, but that it appears in different periods of time. In addition, the factors that are contemplated among the mentioned categories usually develop simultaneously, which contributes to the complexity of analysis and solution of this phenomenon. Also, the characteristics of the place of residence of individuals
have a significant influence on the process of leaving the place of origin.
