The term interdiscipline or inter-discipline means an organizational unit that involves two or more academic disciplines, but which have the formal criteria of disciplines such as dedicated research journals, conferences and university departments. It is related to interdisciplinarity, but it is a noun used for a certain kind of unit (academic discipline). As shown in the example of demography below a field may be both a discipline and an interdiscipline at the same time. The example of Information science demonstrates that a field may be regarded as a discipline in some countries but an interdiscipline in other countries.
