Taiwanese aborigines or Formosan people (Chinese: 臺灣; pinyin: Táiwān yuánzhùmín; Pe̍h-ōe-jī: Tâi-ôan gôan-chū-bîn; literally: "Taiwanese original inhabitants") or Austronesian Taiwanese are the indigenous peoples of Taiwan, who number more than 530,000 and constitute nearly 2.3% of the island's population. Recent research suggests their ancestors may have been living on Taiwan for approximately 5,500 years in relative isolation before a major Han immigration began in the 17th century. Taiwanese aborigines are Austronesian peoples, with linguistic and genetic ties to other Austronesian people. Related ethnic groups include those of Timor-Leste, the Philippines, Indonesia, Malaysia, China, Japan, Madagascar and Oceania. The issue of an ethnic identity unconnected to the Asian mainland has become one thread in the discourse regarding the political status of Taiwan.
