Whether diasporas can help foster development depends 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 countries of origin. This chapter presents a panorama of the diasporas, with a focus on highly educated migrants and labour market outcomes, prior to and after the economic crisis. Looking forward, the chapter also presents data on the desire to emigrate for different population groups, based on the results of the latest Gallup World Poll Survey.
