Academic Mobility and Migration: What We Know and What We Do Not Know

Although internationalisation of the scientific world is a key issue in public attention and policy, the actual information base on migration and mobility of 'teachers in higher education', 'scholars', 'academics' or 'researchers' has remained weak. Most available statistics focus on 'foreign' students or 'foreign' scholars rather than persons mobile for purposes of learning and academic/research work, and provide information only on a single moment rather than on the life course of moving between countries. In recent years, some surveys of the 'academic profession' and 'researchers' have been undertaken primarily in economically advanced countries or especially in European countries that provide an overview on various modes, e.g. migration prior study, short-termstudent mobility and mobility for the whole degree programme, mobility in the phase of doctoral education and training, professional mobility in various stages of the professional career and finally shorter visits linked to academic and research work. All available information suggests that substantial differences exist by country and that no signs of convergence are visible. Moreover, surveys confirm that international experience is a frequently valuable asset of academic research careers but often is viewed as less beneficial than conventional wisdom suggests.
