  Political scientists have put forth a number of theoretical frameworks relating to migration, offering different perspectives on processes of security, citizenship, and international relations. The political importance of diasporas has also become in the 21st century a growing field of interest, as scholars examine questions of diaspora activism, state-diaspora relations, out-of-country voting processes, and states' soft power strategies. In this field, the majority of work has focused on immigration politics, viewing migration from the perspective of the country of destination. With regard to emigration processes, political scientists have expanded on Albert Hirschman's framework on '"voice" vs. "exit" to discuss how emigration affects the politics within countries of origin.
