“An improved understanding of migration to the EU.”

The problem

The EU’s Member States, particularly those of western Europe, are a constant economic attraction for migrants from non-union countries. There is very little detailed information on the numbers or origins of these migrants with which to develop and implement appropriate policies. If social and economic benefits are to be maximised and potential difficulties minimised, there is a pressing need for more reliable information.

CLANDESTINO  Undocumented migration: counting the uncountable


CLANDESTINO will collate data on undocumented migration from selected EU countries. It will carry out a comparative analysis of these data, and review the ethical and methodological issues involved in data collection, elaboration and use. The project will then propose new methods for evaluating and classifying undocumented migration in the Union. The project will focus on a representative range of west European destination countries and key transit countries en route to the EU, notably Turkey, Ukraine and one Maghreb country. CLANDESTINO will also consider factors affecting the shift between legal and undocumented status among migrant populations.

Contribution to policy development:

  • CLANDESTINO will improve the quality of information and understanding of undocumented migration to and between selected EU Member States.
  • The project will improve the quality of information on the effect of undocumented migration on labour markets and economic growth; crime, public order and citizens’ sense of security; the management of legal migration and asylum.
  • CLANDESTINO will develop recommendations for an ethical policy for managing undocumented migration.
  • The project will enhance working relationships and information flow between academics who study the problem and the policy-makers who need to manage it.
