Welcome, and thank you for arriving here with a question rather than an assumption. I have spent months with mortality tables, ministry press releases and survey annexes spread across my desk, and years before that writing about Nigerian health data for a living. So when a reader asks me what is the life expectancy in Nigeria, I have stopped giving the tidy one-number answer. I give three, because the way demographers build these estimates produces genuinely different results depending on whose torch you shine into the dark.

Here is the short version. Then I will spend the rest of this piece explaining why the short version misleads almost everybody who reads it.

The United Nations World Population Prospects revision for 2026 puts Nigeria at roughly 55 years at birth. That figure currently ranks Nigeria last out of 197 countries. The global average sits at about 73.3 years.

Now hold that thought, because a Nigerian who reaches sixty-five can expect to live to seventy-seven.

Both statements are true. Both come from the same dataset. Understanding how they sit together is the single most useful thing I can give you in the next four thousand words, and it is the thing almost no headline about Nigerian mortality bothers to explain.

What the life expectancy figure actually measures, and what it does not

Life expectancy at birth is not a prediction about you.

I want to plant that flag early because the misreading is so common, and so quietly demoralising. When a Nigerian in their forties reads that the national figure is fifty-five, the instinctive response is a kind of cold arithmetic about how many years are left. That arithmetic is wrong. Badly wrong, in fact, and in the direction of unnecessary despair.

What the statistic measures is this: take every age group in Nigeria, look at the proportion who died in a single reference year, then imagine a hypothetical newborn who will face exactly those risks, unchanged, for their entire life. The number that falls out is the average age at death for that imaginary cohort.

Notice the two absurdities baked into that method. First, it assumes nothing improves for eighty years, which has never been true anywhere. Second, and more importantly for Nigeria, it loads the entire weight of infant and child deaths onto the average.

That second point is where the whole story lives. When a Nigerian child dies at eighteen months, the calculation records roughly fifty-three unlived years against the national average. When a retired headmaster dies at seventy-nine in Ilesha, having outlived the average by a comfortable margin, the calculation records almost nothing. Child deaths are arithmetically enormous. Adult deaths, statistically speaking, barely register.

Nigeria loses a great many children. The 2024 Nigeria Demographic and Health Survey, which the Federal Ministry of Health and Social Welfare released with unusual candour, found under-five mortality at 110 deaths per 1,000 live births and revealed that 31 per cent of children aged twelve to twenty-three months had received no vaccines at all. Roughly fourteen per cent of Nigerian newborns still do not reach their fifteenth birthday.

Fourteen per cent. Think about that as a classroom rather than a percentage. Then think about what it does to an average.

Rather like judging a school by its mean exam score when a seventh of the pupils never sat the paper and were recorded as zero, the national figure tells you something real about the country while telling you very little about any individual within it.

There is a second complication worth naming, and it is uncomfortable. Nigeria does not actually count most of its deaths. Civil registration captures only a fraction of them, so every mortality figure you will read in this article, including the ones I am about to defend, is modelled from household surveys rather than counted from certificates. The United Nations, the World Bank and the National Bureau of Statistics each apply different adjustments to broadly the same underlying survey data, which is precisely why they disagree.

How much do they disagree? Enough to matter. The UN revision for 2026 gives about 55 years. World Bank derived series have run closer to 56.4 for 2025. The CIA World Factbook, working from different assumptions, publishes something nearer 52.7. Nigeria’s own demographic bulletin has previously put men at 55.1 and women at 57.2.

That is a spread of nearly four years between reputable sources, which should make anybody quoting a single decimal place slightly nervous.

The financing picture behind those numbers has shifted, and shifted in a direction worth acknowledging. In June 2026 the ministry set out a tally of sector gains showing that health insurance enrolment had grown from about sixteen million to more than twenty-two million people in three years, alongside a ₦32.8 billion disbursement to primary health centres and preliminary findings from a 2026 mini survey pointing to gains in antenatal attendance and skilled birth attendance. The machinery underneath that expansion is the Basic Health Care Provision Fund, which draws at least one per cent of the Consolidated Revenue Fund and channels it through primary care, emergency treatment and a dedicated fund for vulnerable groups.

Twenty-two million insured people in a country of well over two hundred million is still under eleven per cent. Progress and shortfall, occupying the same sentence, as they so often do here.

What is the main cause of death in Nigeria, and why it decides the whole figure

If you want to understand the fifty-five, you have to understand what Nigerians actually die of. Not what makes the news. What appears on the modelling tables.

The top four causes have been stable for years and they cluster remarkably tightly. Neonatal disorders account for roughly 12.25 per cent of all deaths, malaria for about 12 per cent, diarrhoeal disease for 11.36 per cent and lower respiratory infections, mostly childhood pneumonia, for 10.85 per cent. HIV follows at around 5.2 per cent, then ischaemic heart disease, then stroke.

Add the top four together and you are looking at close to half of all recorded deaths in the country.

Now notice what those four have in common. Every one of them kills children disproportionately. Sepsis and birth asphyxia in the first month. Malaria and pneumonia and dehydration in the years that follow. None of them are diseases of old age, and none of them are expensive to prevent.

Which cause sits at number one depends on the modelling year you consult, and I have watched malaria and neonatal disorders swap places three times across different vintages. For practical purposes they are joint leaders. If a reader wants a single name to attach to the answer, malaria is the one most people mean, and Nigeria carries a share of the global malaria burden so disproportionate that it is difficult to state without sounding like a typographical error.

But the honest answer is that the leading cause of death in Nigeria is being born in Nigeria and then being under five.

Adult mortality has its own separate story, and it is quietly getting worse while the child picture improves. Non-communicable conditions now account for something close to thirty per cent of deaths nationally. Untreated hypertension is the standout, because it produces no symptoms whatsoever until the stroke arrives. Diabetes, chronic kidney disease and road traffic injury follow. A Guardian editorial in July put the workforce shortage behind all of this in stark numerical terms, noting that of roughly 130,000 doctors on the national register, only about 55,000 are actually practising in the country.

One doctor for several thousand people, in a nation where the clinic may be an hour’s okada ride away over a bad road.

What is the life expectancy in Nigeria: the direct answer

Right. You have been patient, so let me answer the question properly and in one place.

The life expectancy in Nigeria is approximately 55 years at birth according to the United Nations World Population Prospects revision for 2026, which breaks down to about 54.6 years for men and 55.3 years for women, and which currently places Nigeria at the bottom of a global ranking of 197 countries against a world average of roughly 73.3 years. That headline number is depressed overwhelmingly by deaths before age five rather than by short adult lifespans, which is why the median age at death in Nigeria is actually around 64.3 years, nearly a decade above the headline figure, and why a Nigerian who survives to sixty-five can expect to reach roughly 77.2 years. The related entities you will encounter alongside this statistic are healthy life expectancy, which the World Health Organisation puts at about 54.9 years for Nigeria and which measures years lived in full health rather than years lived at all; under-five mortality, currently around 110 deaths per 1,000 live births; maternal mortality, estimated at 512 deaths per 100,000 live births; and the National Bureau of Statistics demographic bulletin, which has historically published slightly higher figures than the United Nations because it applies different adjustments to the same survey base.

So when a Nigerian friend of mine, a fifty-two-year-old surveyor in Ibadan, told me last year that he had “three years left according to the government”, he had made an entirely understandable error. On the same UN data that produced the fifty-five, his actual remaining expectancy at fifty-two is well over two decades.

He was not three years from the exit. He was closer to twenty-five.

That is not a comforting rounding error. It is the difference between planning a pension and not bothering.

What a Nigerian can expect at each milestone age

The table below is the piece of this article I would most like you to photograph and keep. It shows how the expected age at death climbs sharply for every year you have already survived, using the UN 2026 life tables.

Age already reached	Further years expected	Expected age at death	Gap versus the 55 year headline
At birth	55.0	55.0	None, this is the headline
At age 30	40.0	70.0	15 years higher
At age 65	12.2	77.2	22 years higher
At age 70	9.4	79.4	24 years higher
At age 75	7.1	82.1	27 years higher
At age 80	5.2	85.2	30 years higher

Two conclusions fall straight out of that table. The headline figure is the single least relevant number in the column for anybody old enough to be reading this article, and the survival bonus is enormous: clearing childhood alone buys back roughly fifteen years against the national average, while reaching retirement age puts a Nigerian within striking distance of Western European outcomes.

The annual risk figures underneath the table tell the same story from another angle. A Nigerian faces roughly a 6.69 per cent chance of dying during their first year of life. By age thirty that annual risk has collapsed to 0.67 per cent. At sixty it is 2.29 per cent, and only at eighty does it climb to 12.5 per cent.

The dangerous years, statistically, are the first five and then the ones after seventy. The long middle is far safer than the headline suggests.

How long do Nigerian men live compared with Nigerian women?

Nigerian men have a life expectancy at birth of about 54.6 years on the 2026 UN figures, against roughly 55.3 years for Nigerian women. Median age at death runs to 63.7 for men and 64.8 for women.

Now look at the size of that gap. Seven or eight months.

Globally, women outlive men by four to six years, and the gap is remarkably consistent across wealthy and poor countries alike. It shows up in Japan, in Brazil, in Ghana. Biology accounts for part of it and behaviour accounts for the rest, since men everywhere smoke more, drink more, drive worse and visit clinics less.

So why has Nigeria almost erased an advantage that women hold nearly everywhere else on earth?

Maternal mortality. That is the whole answer, and it is a bleak one. At an estimated 512 deaths per 100,000 live births, Nigeria loses women in their twenties and thirties at a rate that mathematically cancels out the biological head start. Every pregnancy that ends in a haemorrhage or an eclamptic seizure or an obstructed labour in a facility with no theatre subtracts decades from the female column.

The near-absence of a gender gap in Nigerian lifespan is not good news for men. It is terrible news for women.

There has been movement here, and it deserves recording. More than 48,000 women have now received free comprehensive emergency obstetric care, including caesarean sections, under the federal maternal health intervention, and the maternal mortality reduction initiative is active across thirty-two states. Facilities inside the programme have reported reductions of around seventeen per cent.

What kills Nigerian men specifically, once they are past childhood, is a shorter and more familiar list. Road traffic injury, which falls hardest on commercial motorcycle riders in cities where a helmet is treated as a personal preference. Occupational hazard in construction, mining and artisanal refining. Insecurity across the north east and the middle belt, which kills men of fighting age overwhelmingly. And hypertension, sitting quietly untreated in millions of chests because a blood pressure reading is not part of ordinary Nigerian life for a trader in Onitsha or a driver in Kaduna.

A blood pressure check costs between ₦500 and ₦2,000 at most Nigerian pharmacies. A stroke costs a family everything they have.

Which country has the lowest life expectancy in the world?

Nigeria. As of the current United Nations revision, Nigeria holds the lowest life expectancy of any country in the world.

I take no pleasure in writing that sentence, and I have checked it against four datasets before doing so.

The position is recent and it is contested at the margins. On the 2026 UN figures Nigeria sits at roughly 54.6 to 55.0 years, with Chad immediately above at about 55.2 to 55.6, then South Sudan, the Central African Republic and Lesotho in the high fifties. Some datasets that use slightly older projections still place Chad or the Central African Republic at the bottom instead. World Bank derived series, which run about a year and a half behind, put Nigeria marginally higher and therefore not quite last.

What is not in dispute is that Nigeria belongs in that group, and that its arrival at the very bottom happened without the country getting worse.

This is the part that took me longest to accept. Nigerian life expectancy has risen from about 35.5 years in 1950 to roughly 55 today, an extra nineteen and a half years bought inside a single human lifetime through immunisation, malaria control, better nutrition and the sheer physical expansion of clinics. That is a real achievement and Nigerians are entitled to claim it.

The country did not fall to last place. It stood still while everyone else climbed past.

Chad and the Central African Republic, both fighting conflict and displacement that Nigeria does not face at anything like the same scale, improved faster over the past decade than the most populous nation in Africa did. That comparison should sting, and I think it is meant to.

Scale is part of the explanation. Moving the average for 230 million people requires a delivery machine that reaches every ward in thirty-six states plus the Federal Capital Territory, and a national figure can conceal enormous internal variation. Under-five mortality in the North West runs roughly three times the South West rate. The national number is an average of two very different countries sharing a passport.

Rural access is the other half. A recent Guardian opinion piece set out the legislative gaps behind that divide with considerable clarity, arguing that Nigeria does not lack the laws so much as the funding and oversight to make the existing ones bite.

Which country in Africa has the highest life expectancy?

Tunisia, on most current rankings, at somewhere between 76.7 and 77.1 years depending on the dataset. Algeria follows very closely at about 76.5 to 76.9, then Cabo Verde around 76.2 to 76.6, with Morocco and Mauritius in the mid seventies.

If you include territories rather than sovereign states, Réunion tops the continent at nearly 84 years, and Mayotte and Saint Helena also outrank every mainland African country. I mention this because rankings that quietly include French overseas departments alongside independent nations are comparing quite different things.

What do the leaders share? Not oil. Not gross domestic product per head.

Algeria has hydrocarbons in abundance and Cabo Verde has essentially none, yet they sit within half a year of each other. What they actually share is near-universal childhood immunisation, low HIV prevalence, a primary care tier that ordinary people use as a first resort rather than a last one, and sustained public health spending.

Nigeria’s 2026 federal health allocation was ₦2.48 trillion out of a ₦58.47 trillion budget, roughly 4.3 per cent. The Abuja Declaration, which African heads of state signed in Nigeria’s own capital back in 2001, committed governments to fifteen per cent.

Twenty-five years, and the host nation has never once hit the target it convened the meeting to set.

The gap between Tunisia and Nigeria is around twenty-two years of life. That is wider than the gap between Nigeria and Japan was in 1960, which tells you the distance is not fixed by geography or history but by choices made repeatedly over decades.

Money leaving the country compounds the problem. A Guardian editorial earlier this year examined the scale of outbound medical spending, and the arithmetic is difficult to look at: hundreds of millions of dollars a year flowing to hospitals in India, Dubai and the United Kingdom, spent by exactly the Nigerians whose political weight might otherwise force domestic facilities to improve.

Seven steps to work out what this number means for you personally

Enough national averages. Here is how to translate all of the above into your own situation, with the measurements that actually matter.

1. Start from your current age, not from birth. Find your age in the milestone table above and use that expected age at death as your working figure. A forty-year-old Nigerian is not operating on a fifty-five year clock, and financial planning built on the headline number will leave you badly short in your seventies.
2. Get a blood pressure reading twice a year from the age of thirty, and write the numbers down. Anything consistently above 140 over 90 warrants a clinic visit rather than a wait. Most Nigerian pharmacies charge ₦500 to ₦2,000 for a reading, which is roughly the price of a plate of amala and less than a single okada trip across Lagos.
3. Have your fasting blood sugar checked annually once you pass thirty-five. A fasting reading at or above 7.0 millimoles per litre on two occasions indicates diabetes, and readings between 6.1 and 6.9 sit in the warning zone. Testing costs about ₦1,500 to ₦4,000 at most laboratories.
4. Complete the full childhood immunisation schedule for every child in your household, not the convenient portion of it. The 2024 survey found only 39 per cent of children aged twelve to twenty-three months fully vaccinated against basic antigens. A partially vaccinated child carries most of the risk of an unvaccinated one, and the critical window closes at around fifteen months.
5. Register with a health insurance scheme even if you are self employed. State social health insurance agencies exist in all thirty-six states, and premiums in several of them start in the low thousands of naira per year. Out-of-pocket payment is the mechanism by which one hospital admission converts a working Nigerian family into a poor one.
6. Plan the delivery journey before the eighth month of any pregnancy in the household. Decide which facility, how you will reach it at two in the morning, and who is holding the transport money. Around half of Nigerian births still happen without a skilled attendant present, and the emergency is not the moment to negotiate a taxi fare.
7. Ask about your ward’s primary health centre at community meetings, and keep asking. The specific question that produces useful answers is whether a midwife is on duty overnight, not whether the building exists. Facilities improve measurably when somebody local is counting, and the ward is the level at which almost every intervention in this article is actually delivered.

None of these seven require a specialist, a referral or foreign currency. That is either encouraging or infuriating, depending on the day you are having.

Final Thoughts on What the Life Expectancy in Nigeria Really Tells You

If you keep one idea from these several thousand words, make it this. The figure of roughly fifty-five years describes a country that loses too many children. It does not describe a country where adults drop dead at fifty-five, and reading it that way will lead you to the wrong conclusions about your own life and about what Nigeria needs.

That distinction is not a consolation prize. It changes the entire policy prescription. A nation whose adults genuinely died in their mid fifties would need cardiology units, oncology centres and dialysis capacity at ruinous expense. A nation losing children to malaria, sepsis, pneumonia and dehydration needs nets, midwives, antibiotics, clean water and a functioning clinic within walking distance of every ward, and needs them at a small fraction of that price.

Nigeria knows this. The surveys are conducted, the plans are written, the targets are published, and primary care visits have risen from roughly ten million a quarter in 2023 to forty-seven million by mid 2025. The machinery is not broken so much as underfunded and switched on inconsistently.

So what do you actually do? Three things. Recalculate your own expectancy from your current age rather than from birth, because the number in the newspaper is not addressed to you. Take the boring middle-aged measurements seriously, since the adult mortality picture is quietly worsening even as the child picture improves. And when a candidate campaigns in your ward, ask about the midwife rota at the health centre rather than the road resurfacing, because only one of those two things is keeping your neighbours alive.

Nineteen and a half years were added to Nigerian lifespan between 1950 and today. There is no law of nature requiring the next nineteen to take as long.

• Work from your own age, not from birth, because clearing childhood in Nigeria buys back roughly fifteen years against the headline figure
• Book a blood pressure and blood sugar check this quarter if you are over thirty, since both conditions are silent until they are catastrophic
• Judge your community by whether its clinic has a midwife on nights, not by what the national statistic says

If the question that brought you here was really about causes rather than counting, my earlier examination of the forces holding Nigerian lifespan down goes considerably deeper into the child mortality arithmetic, the health workforce exodus and the funding shortfall than I have had room for above. And since almost every outcome discussed here traces back to whether a household can absorb a medical bill without collapsing, you may find my breakdown of what it actually costs to run a Nigerian household a useful companion, particularly on the way out-of-pocket payments interact with rent, transport and food.

Key Takeaways

• Nigeria’s life expectancy at birth is roughly 55 years on 2026 United Nations figures, currently the lowest of any country, though sources disagree by up to four years
• The figure is dragged down almost entirely by deaths before age five, which is why the median age at death is around 64 and why a Nigerian reaching 65 can expect to see 77
• The near-absent gap between Nigerian men and women is a direct signature of maternal mortality cancelling out the biological advantage women hold nearly everywhere else

Frequently Asked Questions About Life Expectancy in Nigeria

What is the life expectancy in Nigeria?

Life expectancy at birth in Nigeria is approximately 55 years according to the United Nations World Population Prospects revision for 2026, split between roughly 54.6 years for men and 55.3 years for women. Other reputable sources place it between about 53 and 56 years, since all of them model the figure rather than counting registered deaths.

Does the life expectancy figure mean Nigerians die at 55?

No, and this is the most damaging misreading of the statistic. The figure is an average dragged down sharply by deaths in early childhood, which is why the median age at death in Nigeria is closer to 64 and why anyone reaching 65 can expect to live to roughly 77.

What is the main cause of death in Nigeria?

Malaria and neonatal disorders such as sepsis and birth asphyxia trade the top position depending on the modelling year, each accounting for roughly twelve per cent of all deaths. Diarrhoeal disease and childhood pneumonia follow closely, and together the top four causes account for close to half of all recorded deaths.

How long do Nigerian men live?

Nigerian men have a life expectancy at birth of about 54.6 years on current United Nations figures, with a median age at death of around 64. Road traffic injury, occupational hazards, insecurity and untreated hypertension are the mortality risks that fall most heavily on adult men.

Why is the gap between Nigerian men and women so small?

Women outlive men by four to six years in most countries, but in Nigeria the gap is roughly seven months. Maternal mortality estimated at 512 deaths per 100,000 live births kills women in their twenties and thirties at a rate that cancels the biological advantage women normally hold.

Which country has the lowest life expectancy in the world?

Nigeria currently holds the lowest life expectancy of any country on the latest United Nations revision, with Chad immediately above it and the Central African Republic, South Sudan and Lesotho close behind. Some datasets using older projections still place Chad at the bottom instead, so the exact ordering depends on which vintage you consult.

Which country in Africa has the highest life expectancy?

Tunisia leads Africa at roughly 77 years, followed very closely by Algeria and Cabo Verde, with Morocco and Mauritius in the mid seventies. High immunisation coverage, low HIV prevalence and a primary care tier people actually use explain the difference far better than national wealth does.

Is life expectancy in Nigeria improving?

Yes, though more slowly than in most comparable countries. Nigerian lifespan has risen from about 35.5 years in 1950 to roughly 55 today, but the country slipped to the bottom of the global ranking because other nations improved faster rather than because Nigeria went backwards.

What is healthy life expectancy in Nigeria?

Healthy life expectancy, which the World Health Organisation defines as years lived in full health rather than years lived at all, stands at about 54.9 years for Nigeria. Nigerians who reach sixty can expect roughly fourteen further years of good health on top of that.

How much does Nigeria spend on health compared with the target?

The 2026 federal budget allocated around ₦2.48 trillion to health out of ₦58.47 trillion in total spending, which works out at roughly 4.3 per cent. That falls far short of the fifteen per cent target African governments committed to under the Abuja Declaration signed in Nigeria’s own capital in 2001.

How many Nigerians have health insurance?

Enrolment grew from about sixteen million to more than twenty-two million people between 2023 and mid 2026, according to the Federal Ministry of Health and Social Welfare. That still leaves coverage below eleven per cent of the population, which is why out-of-pocket payment remains the dominant way Nigerians finance their care.

What single change would raise Nigerian life expectancy fastest?

Getting a skilled attendant to every birth would move the national figure faster than any other single measure, since a large share of under-five deaths occur within the first month of life. Only about half of Nigerian births currently take place with skilled personnel present.
