According to the last 2010 population census, the self-identified Chinese Indonesian population is 2,832,510. There is a growth of 17.5% from 2000 census, although some of them are because the census bureau improved its counting methodology between 2000 and 2010. During the 2000 census, it only published data for the eight largest ethnic groups in each province. Because Chinese Indonesians in some provinces did not have a large enough population, they were left off the list. This error was only corrected in 2008 when Aris Ananta, Evi Nuridya Arifin, and Bakhtiar from the Institute of Southeast Asian Studies in Singapore published a report that accounted for all Chinese Indonesian populations using raw data from BPS.
