Our goals and services

Our goal is to provide academics, governments, international organisations and NGOs with information for research and evidence-based evaluation of public policies.

We do not offer information or counselling to individuals interested in acquiring the citizenship of a particular country and we do not encourage experts in our network to answer such requests.
