Nigeria Health Statistics

Nigeria is a pretty unhealthy country. Nigeria performs the best for its smoking rate₁. It does better than average in the prevalence of overweight adults₂. When it comes to most other metrics, Nigeria does not do well. It does worse than average in terms of its adolescent birth rate₃. It falls into the worst 20 for its food aid and health contributions and WHO compliance₄, its alcohol consumption rate₅ (one of the worst in Africa), childhood mortality in the 2020s₆, delivery rate of 7x Infant Immunizations 2011-2015₇, delivery rate of infant DTP immunizations in the 2020s₈ and in its fertility rate₉. And finally, it is second-from-the-bottom for its average life expectancy₁₀. The prevalence of overweight adults has increased by 14% during the last 40 years. Life expectancy in Nigeria in 1990 was 46yrs, much lower than the global average of 64.6. It improved by +6.9yrs in the 30 years from then, but this was so much less of an improvement than the global average (of +7.9yrs) that by 2016-9 it had the lowest life expectancy in the world. Nigeria's peak fertility rate was 6.92 in 1978, but regions in the north are currently above that, at a truly unmanageable 7.4₁₁.

The countries with the best overall approach to public health, in terms of both public policy and individual lifestyle choices, are Monaco, Liechtenstein and Japan₁₃. These countries are worth emulating. And, although often through no fault of the average citizen, the worst countries are Angola, Somalia and S. Sudan₁₃.

42 datasets are used to calculate points for each country, including multiple decades of data on its average life expectancy, its alcohol consumption rate, its fertility rate, its smoking rate, its suicide rate, its food aid and health contributions and WHO compliance, the prevalence of overweight adults, obesity rate, its adolescent birth rate, delivery rate of infant DTP immunizations, delivery rate of 7x Infant Immunizations 2011-2015 and childhood mortality. The regions with the best average results per country are Scandinavia, Europe and The Mediterranean₁₃, whereas the worst are Africa, Micronesia and Melanesia₁₃.

With regard to its average life expectancy, Nigeria comes 2nd-worst in the world; Chad is worst, after .

Increasing longevity, and subsequent aging, is a long-term trend around the world₁₄. Global life expectancy is now over 70; since 2000 it has risen by 6.3 and in 2019 achieved 73.1 years₁₅, as part of a global trend towards better health_16,17, and due to huge portions of the world being gradually lifted out of poverty. It also reflects overall improvements to cultural health, including diet, health services systems, attitudes to exercise and well-being, and also family structure and caring. For decades, Japan was well-known for having the highest average life expectancy₁₈, until the top spot was taken by Hong Kong. The regions with the best life expectancy are Europe (78.4), The Middle East (75.2) and Asia (73.2)₁₀ and the worst, by some way, is Africa (62.8)₁₀.

One effect of rising longevity is the 'demographics crisis'; where an increasing portion of the population is old and retired, putting pressure on services and taxes₁₉. The solution is for aging countries to import younger workers from elsewhere; over time, as birth rates stabilize, geriatric care improves the length of the working life, and population growth calms, this situation will stabilize.

Nigeria ranks 5th-worst in the world with regard to its alcohol consumption rate.

There is nothing wrong with drinking modest and sensible amounts of alcohol but fitness, physical health, mental health and long-term health all suffer as a result of medium- or heavy- drinking₂₀ and the health risks to the baby when pregnant mothers drink₂₁ are well-known. Aside from the effects on the individual, alcohol misuse impacts on entire economies₂₂ via increased health service costs, policing costs and lost days' work. Worldwide, alcohol misuse is "among the top five risk factors for disease, disability and death" and is a "cause of more than 200 disease and injury conditions in individuals, most notably alcohol dependence, liver cirrhosis, cancers and injuries"₂₃. "In 2012... 5.9% of all global deaths, were attributable to alcohol consumption"₂₄. Deaths from chronic alcohol misuse have been rising for decades, and so has violence, abuse, vandalism and crime all associated with alcohol over-use. The aggression and crime associated with alcohol in some Western countries infringes on the human rights of those who want nothing to do with such behaviour. Many of the social effects of alcohol are psychological and cultural; i.e., people don't have to behave criminally or destructively whilst drunk - it is a culturally learned behaviour. Experiments have shown that behaviour can be controlled: Those who do not wish to behave badly whilst drunk, will not do so.

Nigeria comes 8th-worst in the world in terms of its fertility rate.

The fertility rate is, in simple terms, the average amount of children that each woman has. The higher the figure, the quicker the population will grow, although, to calculate the rate you also need to take into account morbidity - the rate at which people die. If people live healthy and long lives and morbidity is low, then, 2.0 approximates to the replacement rate (two new children for each set of parents who die), which would keep the population stable. If all countries had such a fertility rate, population growth would end. The actual replacement rate in most developed countries is around 2.1, once you take mortality into account₂₅. The highest fertility rate ever detected in a single year was in Yemen in 1985, at 8.86.₂₆

For more, see:

• "The Population of the Earth" by Vexen Crabtree (2019).

Nigeria's fertility rate is unequal_27,11. In Lagos in the South, "women can expect to give birth to an average of 3.3 children during their lifetimes, which is what the world´s fertility rate was in 1990" yet in Katsina state in the north, the rate is over double that, at 7.4₁₁. Some of the factors are poverty, religion and education; the north being much poorer and mostly Muslim, and south being better-off and mostly Christian₂₈. Conservative religion in Nigeria views a large family as a blessing, encourages men to have multiple wives and discourages the use of contraception₂₇. It's not just religion, of course; in the West it was Christian communities that maintained very high fertility rates for a long time after the rest began to worry about overpopulation and sustainability. In terms of education, better education stabilizes and reduces the fertility rate towards sustainable values, but, in Nigeria public schools are controlled and funded by each state, giving the north a permanent advantage. The different in fertility rate is both a symptom, and a cause, of poverty, and this will impact on economic inequality in the country.

In terms of data, the HTF SAMDI takes account of average fertility whilst counting economic inequality in a separate data table. Most of these issues can be resolved through harmonizing the country socially, but, the religious divide has entrenched the two halves against each other. In the long-term, secularisation will help, but for now, Nigeria remains strongly religious. There may be difficult times ahead.

Nigeria ranks best in the world regarding its smoking rate.

Cigarettes are the most lethal consumer product on the planet, responsible for over 7 million deaths annually₂₉ and therefore the biggest preventable cause of disease in the world₃₀. A billion people smoke₃₁. The tobacco industry has resisted with misinformation and well-funded public-relations campaigns, opposing and undermining health measures wherever it can; if defeated, firms continue the same abuses in other countries₃₂. The industry has such rich and influential lobbies that most governments find it difficult to make progress in curbing smoking rates.

If you smoke, you are more likely to drink. If you smoke or drink, you are also more likely to do drugs. Only 15% of men in the highest professional classes smoke, but 42% of unskilled workers do₃₃. Smoking is higher amongst those who are already in trouble: single mothers smoke at 55%, most homeless do and practically all drug addicts do₃₃. Smoking during late pregnancy reduces the IQ of babies by an average of 6.2 points₃₄ and causes increased antisocial behaviour. Aside from the financial cost to taxpayers and the health costs to individuals, indirect negative economic effects result from increased rates of disease and sick days lost from work₂₉.

For more, see:

• " The Side Effects of Smoking. Which Countries Smoke Most?" by Vexen Crabtree (2025).

In the 2000s, Nigeria was one of only 7 countries whose average smoking rate was less than 10%, and on average in the 2020s (so far) it has achieved the lowest smoking rate in the world.

Regarding obesity rate, Nigeria comes 40th in the world.

About one third of the global population is overweight or obese₃₆. It's more serious than simply being overweight and causes a range of systemic health conditions including the development of Type 2 diabetes_37,38, muscle and bone degradation including osteoarthritis₃₇, cardiovascular disease (i.e. heart disease)₃₇, substantial disability₃₇, cancers (endometrial, breast and colon)₃₇, the acceleration of the ageing process₃₉ and decreased life expectancy_37,39. Health systems have to routinely cope with resultant complications, and cultural changes are having to be made₄₀, impacting on transport, resources and workplaces, with measurable effects on national economies, diverting time and resources away from other issues. In 2000, it was the world's most costly epidemic₄₀, and has continued to get worse across all regions of the world every decade since₄₁; from 2000 to 2019 diabetes has caused a 0.14-year slowdown in the increase in healthy life expectancy₄₂.

The causes are lifestyle and culture_43,37, not genetics_44,45. Causes are processed foods, low levels of physical exercise, over-indulgence, poor choices in food products and poor knowledge of nutrition. Health experts have warned that there is no medical solution: prevention is the only possible route to reduce the cost of obesity₄₆ but the situation is made much worse by well-funded advertising campaigns by food manufacturers selling cheap mass-produced food. Even many so-called "health foods" contain well over recommended limits of fat, salt and sugar₄₇ and a range of popular fad diets capitalize on miseducated consumers to buy into costly and nonsensical schemes that falsely promise quick results₄₈.
