Immigration is the international movement of people to a destination country of which they are not usual residents or where they do not possess nationality in order to settle as permanent residents. Commuters, tourists, and other short-term stays in a destination country do not fall under the definition of immigration or migration; seasonal labour immigration is sometimes included, however.
The global population of immigrants has grown since 1990 but has remained constant at around 3% of the world's population.

The Iron Curtain in Europe was designed as a means of preventing emigration. "It is one of the ironies of post-war European history that, once the freedom to travel for Europeans living under communist regimes, which had long been demanded by the West, was finally granted in 1989/90, travel was very soon afterwards made much more difficult by the West itself, and new barriers were erected to replace the Iron Curtain." —Anita Böcker
Human migration is the movement of people from one place to another, with intentions of settling, permanently or temporarily, at a new location. The movement often occurs over long distances and from one country to another, but internal migration is the dominant form of human migration globally.
