in the lowland urban centers of both the North and the South. Of the other minority groups, thirty, comprising 68 percent of the minority population, resided in the North, while the remaining twenty-two groups, comprising 32 percent of the minority population lived in the South. The size of each community ranged from fewer than 1,000 to as many as 0.9 million persons, and 10 major groups comprised about 85 percent of the minority population.

The sedentary groups, the more numerous of the two kinds, are engaged mainly in the cultivation of wet rice and industrial crops; the nomadic groups, in slashand -burn farming where forested land is cleared for a brief period of cultivation and then abandoned. Both groups inhabit the same four major areas: the northern Chinese border region and the uplands adjacent to the Red River Delta, the northwestern border region adjoining Laos and China, the Central Highlands and the area along the Giai Truong Son, and parts of the Mekong River Delta and the central coastal strip.
