An outdated designation formerly used for the architecture of certain people considered to be outside the spheres of influence of other, politically dominant cultural groups; was used especially concerning communities in sub-Saharan Africa, the Pacific Islands, and native tribal groups throughout the Americas. Use instead other terms, such as "vernacular architecture," or use the most specific name known for the culture of origin.
