Leptorrhine (narrow) noses are very common and appear in almost all non-tropical regions of the Northern Hemisphere. Most Europeans show leptorrhine noses as well as many people from India. Much of Siberia and China is leptorrhine just like most Turkic groups. Towards South East Asia leptorrhiny becomes rarer. Much of the arid regions in North and East Africa are leptorrhine (e.g. it is typical for Ethiopids). It also dominates in most cool and temperate regions of North America, from the Plains to the forest, and only becomes rarer in the subtropical areas (e.g. Mexico). Similarly, in South America leptorrhiny appears mainly in regions with subtropical or temperate climate. Thus, leptorrhiny dominates in Patagonians and many groups of the Southern Andes.
