Empirically, there is a lack of knowledge about this situation, meaning that EU governments currently have few means of gauging the future fiscal implications of current migration, in terms of pensions, health and housing, for example. This paper aims to draw conclusions about the decision likely to be faced by today’s migrants when they retire by analysing past decisions under similar circumstances. We explore the situation of EU migrants who moved from the South to North in the early years of European integration, using data from the OECD’s new Database on Immigrants and the European Commission’s Survey of Health, Ageing and Retirement in Europe (SHARE). This data indicates that a large proportion of migrants stayed in their host country on retirement, notwithstanding a financial situation significantly worse than average and often below the relative poverty line.
