Originally, circa 17th to 18th century, the dwellers of Batavia were identified according to their ethnics of origin; either Sundanese, Javanese, Malays, Ambonese, Buginese-Makassar, or Arabs and Chinese. This was shown in the Batavia census record that listed the immigrant's ethnic background of Batavian citizens. They were separated into specific ethnic-based enclaves "kampung"s, which is why in today's Jakarta there are some regions named after ethnic-specific names such as; Kampung Melayu, Kampung Bali, Makassar, and Kampung Ambon. These ethnic groups merged and formed around the 18th to 19th centuries. It was not until the late 19th or early 20th century that the group – who would become the dwellers of Batavia, referred to themselves as "Betawi", which refers to a creole Malay-speaking ethnic group which has a mixed culture of different influences; Malay, Javanese, Sundanese to Arabic and Chinese. The term "Betawi" was first listed as an ethnic category in the 1930 census of Batavia residents.
