About two-thirds of Nigeria lies in the watershed of the Niger River, which empties in to the Atlantic at the Niger Delta, and its major tributaries: the Benue in the northeast, the Kaduna in the west, the Sokoto in the northwest, and the Anambra in the southeast.
Naira (NGN; symbol ₦) = 100 kobo. Notes are in denominations of ₦500, 200, 100, 50, 20, 10 and 5. Coins are in denominations of ₦1 and kobo 25, 10, 5 and 1.
The culture of Nigeria is shaped by Nigeria’s multiple ethnic groups. The country has over 50 languages and over 250 dialects and ethnic groups. The three largest ethnic groups are the Hausa-Fulani who are predominant in the north, the Igbo who are predominant in the southeast, and the Yoruba who are predominant in the southwest.
