The population of
Borneo consists mainly of Dayak ethnic groups, Malay, Banjar,
Orang Ulu,
Chinese
and Kadazan-Dusun.
The religion of the majority of the population is Muslim, and some indigenous groups continue
to practice animism.
Meanwhile, approximately 91% of the Dayak are Christian, a religion introduced by missionaries
in the 18th century. In the interior of Borneo are the Penan, some of who
still live as nomadic hunter-gatherers. Some coastal areas have marginal
settlements of the Bajau (sea gypsies),
who historically lived in a sea-oriented, boat-dwelling, nomadic culture.
