Однако в регионах и странах мира он существенно различен:Миграция населения Главные миграционные потоки International Migration: Recent Trends Figure 5 Major International Migration FlowsMigrants can be divided into five main categories: settlers, contract workers, professionals, unauthorised workers, and asylum seekers and refugees.Settlers These are people who intend to live permanently in their new country. Most head for the main countries of settlement, notably the United States, Canada and Australia. Around one million travel per year, the majority of whom are joining close family members.Contract workers They are admitted to other countries on the understanding that they will stay only for a specific period: the length of their contract. Some are seasonal workers. Others will be on longer-term contracts, of a year or more. Most are to be found in the Gulf countries.Professionals These include employees of transnational corporations who are moved around from one country to another. These tend to involve fairly small numbers, typically fewer than 1% of people employed in local affiliates are expatriates.Unauthorised workers Sometimes called undocumented or illegal immigrants. There are significant numbers in most immigration countries. Some have been smuggled in, others are overstaying their visas, or are working on tourist visas.Asylum seekers and refugees Asylum seekers have left their homes to escape danger; if their claims for asylum have been accepted they are then classified as refugees . In some cases of mass flight, however, when thousands of people escape across a border they are accepted as refugees without going through the individual process.These are the main categories but there are many other possibilities.(Source: Stalker s Guide to International Migration)+++Figure 7 Permanent and long-term immigration flows into selected OECD countries by main categories in 2001Showing Migration Flows as Sankey Refugee flows in Middle East, Africa and Asia in 2006 (clustered quantities)
