Across Europe, concerns about irregular migration have dominated media headlines and shaped recent elections. Discussions of and policymaking related to irregular migration are often a numbers game, fueled by the latest estimates of changing migration trends and migrant populations. Data on irregular migration also influence decision-making, advocacy, and strategic and operational planning of a wide range of governmental and nongovernmental actors.

But despite playing such important roles, data on irregular migration are often inadequate—either lacking altogether, uneven, or difficult to access. This has consequences for policymakers, service providers, and other stakeholders that would benefit from better access to reliable data.

This MPI Europe policy brief explores obstacles that hinder the effective collection and use of irregular migration data, how this affects policymakers and other actors, and potential avenues for strengthening the evidence base. This study, which is part of the Measuring Irregular Migration and Related Policies (MIrreM) project, draws on insights shared in workshops and interviews by policymakers, subject matter experts, NGO representatives, and other stakeholders.

Combatting’ irregular migration is one of the key challenges to migration management at EU level. The present book addresses one of the most pressing structural problems regarding the EU’s return policy: the low return rate of irregularly staying migrants. In this regard the EU Return Directive obliges Member States to issue a return decision, yet only 40% of such decisions are enforced annually. Moreover, despite the political and legal efforts, the EU is not making any significant progress in enforcing the rules it has laid down in the Return Directive. The legislation of EU Member States may, however, serve as a source for possible solutions to ‘combat’ the problem of irregularly staying migrants. This is why the book compares the system of regularisations in Austria, Germany and Spain. Regularisations constitute an effective alternative to returns because they terminate the irregular residence of migrants, not through deportation, but rather by granting a right of residence. Regularisation is therefore understood as each legal decision that awards legal residency to irregularly staying migrants. As is shown by the examination and comparison of regularisations in Austria, Germany and Spain, differentiated systems of regularisation exist at national level. However, EU regularisations supplementing the present return policy would be more effective at ‘combatting’ irregular migration at EU level.

This open access book provides an analysis of the functioning, consequences and inherent limitations of internalised immigration control. By adopting the perspective of irregular residents as well as local service providers, the book sheds new light on the intricate mechanisms that either help or hinder the diffusion of immigration control into concrete institutional settings, like schools or hospitals. A simple and innovative analytical framework enables the systematic comparison of three different spheres of service provision across two distinct local as well as also national contexts. This is necessary to understand the complex interplay between formal law and policy, the intrinsic rules and logics operating within institutions, and the ethical or practical obligations and constraints attached to particular roles and professions. Based on empirical findings and rigorous analysis, the book argues that internalised control is part of the problem that irregular migration poses for society, rather than constituting a potential solution to it.
