Igbo-speaking peoples can be divided into five geographically based subcultures: northern Igbo, southern Igbo, western Igbo, eastern Igbo, and northeastern Igbo. Each of these five can be further divided into subgroups based on specific locations and names. Today Igbo-speaking individuals live all over Nigeria and in diverse countries of the world. As a people, however, the Igbo are located on both sides of the River Niger and occupy most of southeastern Nigeria. The Igbo blacksmiths of Awka are renowned for their ironsmithing. Men's wood carving and women's pottery and patterned woven cloth are of very high quality, and Igbo carpenters can be found all over Nigeria. The stylized character of Igbo masks consists of figures with beak noses, slit eyes, and thin lips.
