Existential migration is a term coined by Greg Madison (2006) in Existential Analysis, the journal of the Society for Existential Analysis. Madison's term describes expatriates (voluntary emigrants) who supposedly have an "existential" motivation to travel, unlike economic migration, simple wanderlust, exile, or variations of forced migration. ‘Existential migration’ is conceived as a chosen attempt to express something fundamental about existence by leaving one's homeland and becoming a foreigner.
