Private companies and public institutions increasingly want research programs that focus on ethnic and religious minorities. Companies want to tailor their offer to specific target groups and institutions aim to combat discrimination although some politicians do not rule out so-called positive discrimination for minorities. Identifying people within a specific ethnic or religious group is not easy. We normally have three classifications: immigrants, ethnic minorities and religious minorities. These terms may be defined and interpreted differently depending on the language and country involved, which is why it is crucial for the research industry to agree on unambiguous and globally valid definitions. The work of the EU Agency for Fundamental Rights (FRA) could be helpful in this respect.
