In this final section, we want to briefly discuss some aspects from the seven chapters of this book, in particular what they tell us about important points, missing or underdeveloped perspectives and challenges regarding transition policies and research on young people's transitions and agency at a time of rapid social and economic transformation. We believe that the contributions are well placed to make contributions to new, critical research, as they depart from different theoretical, methodological and actor perspectives and thus look at the transition landscape from various viewpoints. The contributions by Tero Järvinen (Chapter 2) and Johanna Rosa Arnardottir (Chapter 3) build on large datasets that enable longitudinal comparisons, including over the years of the deep economic recession from 2008 to 2010. They both address the trajectories of NEETs-young people and young adults who are not in employment, education or training, and, importantly, their analyses nuance the picture of the vulnerability of this group. Comparisons, across time and across countries, of school-to-work transitions help to increase knowledge about what shapes youth conditions and may complement critical qualitative analyses in this field. While international comparisons of NEET rates have become common over the last decade, other aspects of young people's transitions are more difficult to compare, because of the different constructions of post-compulsory education and training, different definitions of unemployment and weak connections to the labour market etc.
