Brubaker argues that the initial expansion of the use of the phrase extended it to other, similar cases, such as the Armenian and Greek diasporas. More recently, it has been applied to emigrant groups that continue their involvement in their homeland from overseas, such as the category of long-distance nationalists identified by Benedict Anderson. Brubaker notes that (as examples): Albanians, Basques, Hindu Indians, Irish, Japanese, Kashmiri, Koreans, Kurds, Palestinians, and Tamils have been conceptualized as diasporas in this sense. Furthermore, "labor migrants who maintain (to some degree) emotional and social ties with a homeland" have also been described as diasporas.
