Abstract
Life expectancy is a discreet but striking measure of a nation’s health, fairness and opportunity. In Nigeria that story is gradually improving but the gap is still wide. Nigerians live an average of about 55 years, according to recent global estimates — almost 73 years worldwide and about 64 in sub-Saharan Africa. Two decades of progress is real but fragile. The numbers for child mortality now are also lower, thanks to improved immunization and maternal health programs. But income gains are still held back by rising deaths from hypertension, diabetes, road traffic accidents, malaria and tuberculosis. Nigeria’s health care system has profound structural problems. Public health spending lags far behind continental targets, doctor-to patient ratios are low and health insurance coverage extends to only a small fraction of people. Most households still pay out of pocket, often driving families further into poverty. Poor data systems also make planning and accountability harder. Not just healthcare — social and environmental conditions can be decisive. All these factors lead to unequal survival outcomes: poverty, low education levels among women, inadequate sanitation and garbage disposal facilities, unsafe water supply, air pollution and insecurity in certain regions. These recommendations include strengthening primary healthcare systems, expanding digital health systems to reach underserved populations; investing in education and gender equity; addressing environmental risks such as climate change; and ensuring transparent and accountable governance. In the end, longevity isn’t just about medicine; it’s about creating structures that allow every Nigerian to have a fair shot at flourishing.
