The authors compared four countries characterised by a complex state structure – Belgium, Canada, Italy and Spain – and showed that discussions on the integration of migrants have slowly but surely penetrated the interaction between states and between levels of government. For example, specific intergovernmental agreements, councils or committees have been established. Moreover, the integration of migrants has been mainstreamed in intergovernmental discussions in sectoral committees and councils on employment, housing, health and education.
 
The researchers also tested the drivers of cooperation between policy levels. Regions that strive for more autonomy, such as Flanders, Catalonia, South Tyrol and Quebec, are more often in conflict with the central state on integration. The Europeanisation of integration and anti-discrimination policies has led to increased internal cooperation between the federal state and the federated states in Belgium, more so than in other states.

On International Migrants Day, 18 December, Ilke Adam will give a lecture on integration policy in Belgium at Bozar. She will talk about her (radical) solution for Brussels: www.bozar.be/nl/activities/146741-van-integratie--naar-gelijkheidsbeleid-pleidooi-voor-een-radicaal-brusselse-aanpak

Integration, equal opportunities and anti-discrimination is not a matter of one policy level or one policy sector. Like gender equality and sustainable development, it requires intense cooperation and decisiveness.
