This article applies Henri Lefebvre’s concept of rhythmanalysis to an exploration of ethnicity in Hong Kong. It argues that rhythmanalysis has tended to be used in social geography, architectural research, and cultural studies and has been overlooked as a methodological tool in regard to ethnicity. An historic narrative of ethnic diversity in Hong Kong is contrasted with contemporary transformations. It is argued that rhythmanalysis presents an alternative perspective that can deepen knowledge about enduring social patterns that serve to contextualise ethnicity and ethnic relations in a given space. In conclusion, it is argued that there is a need for greater recognition of ethnic diversity in Hong Kong as a means to assert a more confident and secure local identity.
