The Ethnic and Migrant Minorities Survey Question Data Bank (EMM QDB)–which has been co-produced by COST Action 16111-ETHMIGSURVEYDATA, the SSHOC (Social Sciences and Humanities Open Cloud) project, and the FAIRETHMIGQUANT project–is a free online service dedicated to questionnaires used in quantitative surveys undertaken with ethnic and migrant minority (EMM) respondents. The EMM QDB collection can be accessed at https://ethmigsurveydatahub.eu/emmqdb/. To find the EMM QDB collection on the Centre de Données Socio-Politiques (CDSP) of Sciences Po's Colectica Portal, go to the Series entitled, 'Ethnic and Migrant Minorities Survey Question Data Bank Collection.' Users of the EMM QDB will be able to discover and learn about the different questionnaires, including their specific questions, using the 'Search' and 'Explore' functions of the CDSP's Colectica Portal. The EMM QDB is currently in a pilot version. This means that it will only cover questionnaires from surveys that: (1) are covered by the EMM Survey Registry (https://ethmigsurveydatahub.eu/emmregistry/), (2) study the topic of social ties and civic participation; and (3) have been conducted in Croatia, France, Germany, Hungary, Italy, the Netherlands, Norway, Spain, Switzerland, and/or the UK.** **Countries outside of these 10 countries may be included in the pilot version of the EMM QDB. This would occur if a country was a participant of a cross-country survey that meets the aforementioned inclusion criteria of the pilot version.
