Voters in Nigeria will elect a new leader after President Muhammadu Buhari's final term ends, with 18 candidates to choose from. Nigeria is Africa’s most populous country, and it has at least 93 million registered voters, almost 40% of whom are under 35. Nigeria has one of the world’s largest youth populations, with about 64 million people aged 18-35 and a median age of 18. Despite being Africa’s largest economy and one of its top oil producers, Nigeria is suffering an economic crisis. AP video shot by Dan Ikpoyi
