diaspora

A diaspora () is a scattered population whose origin lies in a separate geographic locale. In particular, the word diaspora is used to refer to the involuntary mass dispersion of a population from its indigenous territories, most notably the Jews who were dispersed from the Land of Israel in antiquity (known as the Jewish diaspora). Some other diasporas are the African transatlantic slave trade, the southern Chinese or Indians during the coolie trade, the Irish during and after the Irish Famine, the Romani from India, the Italian diaspora, the exile and deportation of Circassians, the flight or expulsion of Arabs from Palestine, fleeing of Greeks after the fall of Constantinople, Expulsion of the Acadians, and the emigration of Anglo-Saxon warriors and their families after the Norman Conquest of England.Recently, scholars have distinguished between different kinds of diaspora, based on its causes such as imperialism, trade or labor migrations, or by the kind of social coherence within the diaspora community and its ties to the ancestral lands. Some diaspora communities maintain strong political ties with their homeland. Other qualities that may be typical of many diasporas are thoughts of return, relationships with other communities in the diaspora, and lack of full integration into the host countries. Diasporas often maintain ties to the country of their historical affiliation and influence the policies of the country where they are located.
In 2019, according to data released by United Nations with 17.5 million Indian diaspora is world's largest diaspora, followed by 11.8 million Mexican diaspora and 10.7 million of Chinese diaspora.
