Levels of integration of immigrants in the EU and in non-EU countries such as Canada and the United States represent a key topic in research aiming to understand deviations and elaborate policy actions. The EU-funded TIMEUSE project will study the integration of immigrants by applying a new approach based on the amount of time immigrants and natives spend on daily activities. It will explore the differences between immigrants and natives, with particular focus on gender and other characteristics, and establish new metrics to analyse the relationships and the time distribution between and across integrating activities. The research will use exceptionally detailed data on the time-use of a wide range of immigrants and natives residing in several EU Member States, Canada and the United States.
