Manggatal was originally populated sparsely by native
Dusuns of the Bundu tribe or Central Dusunic stock who are ethnolinguistically interrelated to their kinsfolk in the highland/riverine lowland districts of Kota Marudu, Tambunan, Keningau, Telupid, Beluran, Kota Belud and also Ranau as well as the
Bajaus. In the late 19th and early 20th centuries, this native population was supplemented by
Chinese migrants, most of whom were
Hakkas. The Chinese community of Manggatal, which is still dominated by Hakkas, plays an important role in the town's economy as its members own most of the shops in the town. Starting in the 1970s, Manggatal has witnessed a drastic increase in the population of
Filipino and
Indonesian immigrants, many of whom have been naturalised (both legally and illegally) and live in squatter colonies. == Education ==
