9. Nigeria
Nigeria is a very ethnically diverse country with over 500 languages and ethnic groups. The largest ethnic groups include Hausa who make up for about 25% of the entire population, (about 67 million people) Yoruba (21%), Igbo (18%), Ijaw, Kanuri, Fulani etc. The Hausa culture is very similar throughout Nigeria. They practice Islam as their main religion, they raise livestock and grow crops. The Yoruba people, the second largest ethnic group in Nigeria, are usually Muslim or Christian but a large number of them still value the religious beliefs and practices of their ancestors.
