The term "migration stream" refers to a migratory pattern followed by any ethnic group as the group moves from one area to another. A migration stream is largely dependent upon the socioeconomic condition of the local area.
When a large number of people from a specific ethnic group move from one destination to another in search of better jobs, more opportunity or a safer place to live, it creates a migration pattern known as a migration stream. World leaders study migration streams to understand where certain ethnic groups migrate and why.
Labor migration is the most common reason for people to migrate from one area to another. Many immigrants come from underdeveloped countries into developed countries for job opportunities. Migrants also move within their own country as economic stability shifts within different regions.
