Emigrant policies cover any kind of policy that states develop to establish a new relation towards, or keep the links with, their emigrants. Emigrant policies vary among different countries and include programs as diverse as return policies, dual citizenship, the stimulation of remittances and the creation of government agencies to administer emigrant issues. The Emigrant Policies Index (EMIX) is a tool to order and structure the emigrant policies adopted (up to the end of 2015) by 22 states of origin in Latin America and the Caribbean. It includes information about 102 policy indicators, grouped hierarchically along 12 dimensions and two components. Emigrant policies have two main components: (1) policies and (2) the administration setting developed to cope with their design and implementation. The first component summarizes the content of the policies. It is composed of ten subcomponents: citizenship policies, electoral rights, institutional consultation, external obligations, economic policies, social policies, political competition abroad, symbolic policies, cultural policies and exit and transit policies. The second component, administration, accounts for the capabilities of the state to design and implement emigrant policies and is integrated by two subcomponents: the home administration setting and the administration deployed by the given country abroad. All items, attributes, subcomponents and components that integrate the index score between 0 and 1. The EMIX is composed by two aggregation steps. First, subcomponents are aggregated to calculate the POLICY and ADMINISTRATION scores (arithmetic means). In the final aggregation between components (POLICY and ADMINISTRATION), arithmetic mean was used but the authors gave more weight to the POLICY component than to the ADMINISTRATION component.
