According to 2010 population census, 22.3 percent of Chinese Indonesians lived in the capital city of Jakarta, located on the island of Java. When the island's other provinces—Banten, West Java, Central Java, Yogyakarta, and East Java—are included, this population accounted for around half (51.8 percent) of all Chinese Indonesians. This data does not count the number of ethnic Chinese that have foreign citizenship. 8.15 percent of West Kalimantan's population is ethnic Chinese, followed by Bangka–Belitung Islands (8.14 percent), Riau Islands (7.66 percent), Jakarta (6.58 percent), North Sumatra (5,75 percent), Riau (1.84 percent). In each of the remaining provinces, Chinese Indonesians account for 1 percent or less of the provincial population. Most Chinese Indonesians in North Sumatra lived in the provincial capital of Medan; they are one of major ethnic groups in the city with the Bataks and Javanese people, but in the province, they constituted only a small percentage because of the relatively large population of the province, the sizeable Chinese population also has presence in Binjai, Tanjungbalai and Pematangsiantar city. Bangka–Belitung, West Kalimantan, and Riau are grouped around the hub of ethnic Chinese economic activity in Singapore and, with the exception of Bangka–Belitung, these settlements existed long before Singapore's founding in 1819.
