Immigration is the arrival of new individuals into a habitat or population. It is a biological concept and is important in population ecology, differentiated from emigration and migration.
The International Organization for Migration said there are more than 200 million migrants around the world today. Europe hosted the largest number of immigrants, with 70.6 million people in 2005, the latest year for which figures are available. North America, with over 45.1 million immigrants, is second, followed by Asia, which hosts nearly 25.3 million. Most of today's migrant workers come from Asia.[2]
