People - note
Papua New Guinea's indigenous populace is among the most diverse globally; it comprises several thousand distinct communities, many with populations in the hundreds; these groups, defined by their languages, customs, and traditions, have historically engaged in minor tribal conflicts with neighboring groups for centuries; the introduction of modern weaponry and an influx of migrants into urban areas have significantly intensified the effects of this disorder.
