Due to the globalisation of the economy, migratory flows have increased significantly. Unaccompanied foreign minors have become a growing problem in recent years. The objective of this study is to make an analysis from a bibliometric point of view and to identify the main research trends concerning this topic by clusters identification. It has been observed that, above all, there are two main subjects that dominate the scientific literature in this field, the social sciences and medicine. The first one is the clearest in terms of legal and political implications, but the second one is related to the field of determining the age of minors by means of diagnostic tests. As to clusters, the following have been identified: First as a refugee–asylum seeker, second as a refugees–psychology, third as migration, fourth as age determination, and fifth as health care. Finally, the following temporal evolution of the issues dealt with in relation to unaccompanied minors has been observed: War, stress, migration, immigration, risk factors, health, legal aspects and, more recently, vaccination or age determination.
