Throughout human history, migration of human beings is a pre-requisite of human progress and development. Without migration, human being would be doomed to an existence worse than that of the animals. Even animals migrate to seek a better life. The first humans migrated out of Southern Africa thousands of years ago and spread throughout the world and people have been moving about since then. People also migrate because of factors like wars, poverty, discrimination, and for political or even religious reasons. In modern times, people often migrate for security, work and even for education opportunities.

Organised immigrant labour migration and free immigration in Malaysia took place under the British colonial administration in the 19th century. During this period, the British required immigrant labour from China, India and Indonesia to help them in the exploitation of natural resources of the colonised countries establishing plantations and building infrastructure. It is mainly because of immigrant labour provide a steady, adequate and cheap supply of workers at a time when the locals labour was either deemed unsuitable or was not interested in working under the same harsh conditions as migrant labour. This period of free movement into Malaya saw large numbers arriving to work as well as returning home. However, because of free immigration and economic difficulties in the countries of origin, many immigrant workers decide to settle down in Malaya permanently.

Malaysia’s rapid economic development since independence has relied on Malaysian workers moving from rural-to-rural and rural-to-urban areas and immigrant workers, especially from Association of South East Asian Nations (ASEAN) and other Asian countries. In the case of movement from rural-to-rural areas, rapid migration was swift mainly by government intervention in rural development and agriculture. Rural-to-urban migration accelerated after government intervention in urban and industrial development was stepped up, especially after the second Malaysia Plan.

The “push” and “pull” factors at the international level in the region also caused workers to migrate to Malaysia for employment. The accelerated economic development programmes and the sustained high economic growth rates in Malaysia over approximately three decades caused the influx of immigrant workers to meet the increasing demand in the Malaysian labour market.

2.2 WHY PEOPLE MIGRATE

There are many theories that attempt to explain why people migrate. Among others is the “need and stress theory” [30] . This theory holds that every individual has got his own needs to be fulfilled. These needs take various forms including economic, social, psychological and cultural. The higher the chances that an individual’s needs will not able to be fulfilled, the higher the stress he suffers from. If this stress grows beyond tolerable limits, the individual will force himself to move to a different area, which seems to promise possible fulfilment of his needs.
