The Immigrant Integration Barometer survey was conducted within the framework of the project Center for Documentation and Research on Immigrant Integration, funded by the European Fund for the Integration of Third Country Nationals and implemented by the Romanian Association for Health Promotion (ARPS) and the Open Society Foundation (Foundation). The Immigrant Integration Barometer (BII) is a tool that analyzes the extent to which Romanian society values and facilitates the social inclusion of immigrants, especially those from outside the EU. In 2015, the study is in its third edition. The first two editions (2013 and 2014) can be consulted on the website of the Open Society Foundation , and are published under an open license. The Research and Documentation Center on Immigrant Integration project ran for three years, from August 2012 to June 2015. In each of these years, the research component was taken up within roughly the same conceptual framework, developed in the first year (2013) and refined following lessons learned from application and feedback from the immigration research and practice community. Thus, at the end of the three years, the outcome of the research is a robust, field-tested tool for assessing society's openness to immigrants. At the same time, we have a measure of progress over the three years of the project.
