According to the released Statistical Report on Men and Women in Nigeria for 2017, the average life expectancy in Nigeria is 49 years. Based on this report, Nigerian women have a longer life expectancy of 51 years while men are expected to live for just 47 years. This is a drastic reduction from the previous year, 2016, where the life expectancy was estimated to be 55.5 years for men and 57.2 years for women.
Presently, Nigeria has a World Life Expectancy ranking of 178 out of 192 ranked countries. A Nigerian male born in 2018 is expected to live approximately 54.7 years in good health, while a female will live a healthy life of approximately 55.7 years. The average life expectancy at birth in Nigeria is 55.2 years.
Available data shows that Nigerians are more liable to die from sickness and diseases than from any other cause. This is reflective of a problem in the prevailing health and environmental conditions within the country. It is also a pointer to the inaccessibility of good healthcare to the average citizen of the country.
