Empirical studies have found that achieving superdiversity—a substantial increase in the scale and scope of minority ethnic and immigrant groups in a region—can provide certain economic benefits, such as higher levels of worker productivity and innovation. Superdiversity can also provide a boost to local demand for goods and services.
