This book addresses the legal feasibility of ethnic data collection and positive action for equality and anti-discrimination purposes, and considers how they could be used to promote the Roma minoritys inclusion in Europe. The books central aim is to research how a societal problem can be improved upon from a legal perspective. The controversy surrounding ethnic data collection and positive action severely limits their use at the national level. Accordingly, legal and political concerns are analysed and addressed in order to demonstrate that it is possible to collect such data and to implement such measures while fully respecting international and European human rights norms, provided that certain conditions are met. Part I focuses on ethnic data collection and explores the key rules and principles that govern it, the ways in which this equality tool could be used, and how potential obstacles might be overcome. It also identifies and addresses the specific challenges that arise when collecting ethnic data on the Roma minority in Europe. In turn, Part II explores positive action and the broad range of measures covered by the concept, before analysing the applicable international and European framework. It reviews the benefits and challenges of implementing positive action for Roma, identifies best practices, and gives special consideration to inter-cultural mediation in the advancement of Roma inclusion. The book concludes with an overview of the main findings on both topics and by identifying three essential elements that must be in place, in addition to full respect for the applicable legal rules, in order to combat discrimination and achieve the inclusion of Roma in Europe by complementing existing anti-discrimination frameworks with the collection of ethnic data and the implementation of positive action schemes.
