Connecting with Emigrants : A Global Profile of Diasporas The potential of diasporas as a source of economic and social development in origin countries and whether diasporas could help foster development depend on their characteristics such as size composition skill levels and degree of concentration but also on the degree of integration into the destination countries and the economic political and social environment in origin countries. Governments of origin and destination countries can indeed facilitate the involvement of diasporas by supporting networks by facilitating communication channels with the country of origin by creating an enabling environment or – more directly – by easing skill mobility and use. In this regard the capacity to characterise the profile of diasporas is instrumental. This joint OECD AFD publication includes 140 country notes summarising diaspora sizes including the number of children of migrants born in the destination countries; the characteristics of emigrant populations (gender age education labour market outcomes); the numbers and main destinations of international students; recent migrant flows to OECD countries; and information on the desire to emigrate of different population groups. The country note information is grouped into six regions: Asia and Oceania; Latin America and the Caribbean; OECD countries; Non OECD Europe and Central Asia; Middle East and North Africa; and Sub Saharan Africa. The situation in each region is introduced by a separate chapter which looks at historical migration trends the main characteristics of diasporas originating from the region and likely future developments and challenges.
