Action Plan on the integration of third country nationals

European societies are, and will continue to become, increasingly diverse. Today, there are 20 million non-EU nationals residing in the EU who make up 4% of its total population. Human mobility, in varying degrees and for a variety of different reasons, will be an inherent feature of the 21st century for Europe as well as globally, meaning the EU not only needs to step up gear when it comes to managing migration flows, but also when it comes to its integration policies for third-country nationals.
