The Naso and the Bri-Bri are the smallest indigenous groups in the country. The population of both towns, combined, amounts only to approximately 2% of the total population of natives in Panama. The Bri-Bri inhabits the shores of the rivers Yorkin and Sixaola, in territories located to both sides of the rich Panama-Coast border, in the extreme northwest of the country. The Naso occupy the borders of the Teribe river, this being the reason why they are called their name. Both groups live in small communities scattered by moved away sylvestrian territories of the urban centers.
