The Philippines is inhabited by more than 182 ethnolinguistic groups, many of which are classified as "Indigenous Peoples" under the country's Indigenous Peoples' Rights Act of 1997. Traditionally-Muslim peoples from the southernmost island group of Mindanao are usually categorized together as Moro peoples, whether they are classified as Indigenous peoples or not. About 142 are classified as non-Muslim Indigenous people groups, and about 19 ethnolinguistic groups are classified as neither Indigenous nor Moro. Various migrant groups have also had a significant presence throughout the country's history.
