More than one million people left their home countries and fled to Germany in the years 2015 and 2016. Now, the great challenge for both refugees and the host country is to integrate them successfully into society and the labor market. In order to devise and implement effective measures to support this process, it is crucial to have a precise and up-to-date picture of the living situation of refugees, their attitudes and efforts, as well as which obstacles they identify for a successful integration.

With the study “Life and Integration in Germany”, we want to provide this information. In particular, we want to conduct interviews with refugees in more than 40 residences in the districts of Ortenau and Lörrach as well as in the city of Freiburg to gain insights about the following topics:


1. The current life situation, attitudes, and integration experiences of refugees, and

2. Their efforts and level of success in entering the labor market.


Additionally, we want to examine how much the refugees use their smartphones in their integration efforts, e.g., by using language apps or online dictionaries, to get in touch with Germans, or to search for a job. This topic has increased in importance over the last years, as smartphones play an ever larger role for people fleeing from their home countries. As part of this study, we want to evaluate the effects of this development.

Data policy


This study only collects data from participants with their informed and explicit consent. They can unilaterally end their participation at any time and with immediate effect.

The anonymized data are exclusively saved on protected servers in Germany. Throughout the data collection phase, data storage takes place predominantly at our partner, the P3 insight GmbH with headquarters in Aachen, Germany. Afterwards, the data will be transferred to the Mannheim Center for European Social Research (MZES). Both institutions have implemented all legally prescribed and recommended data protection policies and constantly examine and update their data security measures.

All data transmissions will be conducted using advanced encryption standards.

The collected information will only be used for our research within the scope of the “Life and Integration in Germany” study. We do not share the data with any company or other third party for commercial purposes. After the completion of the project, the anonymous data set will be stored in a public archive in order to allow other researchers to work with it.
