Resumen: Spain has an eventful migration history. After seven decades as an emigration country from the beginning of the last century to the 1970s, it become the leading immigration country of the European Union in the early twenty-first century, with annual net migration of more than 700,000 people in 2007. The economic crisis of 2008 put an end to this situation, and net migration became negative in 2012. The number of entrants dwindled, and many residents –?immigrants in particular?– started leaving the country. This movement of “immigrant out-migration” is analysed here by Gemma Larramona using data from the Spanish population registers which record departures from the country. She distinguishes between return and non-return migration of immigrants, and analyses the determinants of these two types of out-migration: individual characteristics of migrants, economic characteristics of origin and destination countries.
