The current volume of IMISCOE-AUP Textbook Series encompasses 25 theoretical papers that have an impact on research in Europe or reflect a European perspective on international migration and immigration integration.

Over the project's lifetime, the project team investigated the scope, availability and comparability of quantitative data in the area of migration, integration and discrimination in Europe, studying available statistical data and data collection in 29 countries.

In 2021, there were an estimated 2.3 million immigrants coming to the EU from non-EU countries and about 1.1 million people from the EU who emigrated to a country outside the EU. This is an important increase compared with 2020.
