The life expectancy in Nigeria is the lowest in West Africa. The life expectancy is around 47 years for both men and women, according to the Nigeria Center for Disease Control. This very low number can be attributed to the country’s health issues. Nigeria’s AIDS epidemic is a major player in the country’s low life expectancy. Also, Nigeria has a high child and maternal mortality rate and widespread polio.
