Religious affiliation in Nigeria is strongly related to ethnicity, with rather distinct regional divisions between ethnic groups. The northern states, dominated by the Hausa and Fulani groups, are predominantly Muslim while the southern ethnic groups have a large number of Christians. In the southwest, there is no predominant religion.
Initially, New Year is considered to be a festival drawn out of the religion of Christianity, in almost all parts of the country other than the northern part. However, the thought process got more liberal, and even people from other beliefs including the prominent Islamism, started celebrating New Years Eve with ecstasy and enthusiasm. However, the ways with which different religious followers celebrate it is slightly different from others.
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.
