Out-of-School Children in Nigeria: What the Numbers Actually Say

Nigeria has the largest out-of-school population of any country. Beyond that, the numbers get complicated, and this article is partly about why.

The competing figures

All four are attributed to UNICEF. They are not contradictory in the way they appear.

The near-certain explanation is different age bands. A figure covering primary-age children only — roughly 6 to 11 — will be far smaller than one covering primary plus junior secondary, roughly 6 to 15. A humanitarian caseload figure counts something different again.

We could not confirm the age bands behind either the 10.2 million or the 18.3 million figure, which is the crux of the discrepancy. Our advice: use the range, state the source and date, and do not present any single number as settled.

What none of the figures is in dispute about is the direction and the scale. Whether it is ten million or nineteen, it is the largest such population in the world.

The northern concentration

On the 10.2 million base, Kano, Katsina and Jigawa together account for 16% — Kano nearly 900,000, Jigawa over 330,000, Katsina over 300,000.

On the 18.3 million base, the same three states account for nearly 30%, around 5.5 million.

Either way, three north-western states carry a disproportionate share.

Why children are out of school

The documented drivers cluster into four groups.

Cost. Basic education is constitutionally free, but uniforms, books, levies and transport are not. For a household near subsistence, the direct cost of sending a child to school competes with food.

Opportunity cost. A child herding, farming or trading contributes to household income. School removes that contribution for years before it returns anything.

Insecurity. School abductions have a compounding effect well beyond the children taken. After the Kebbi and Niger abductions of November 2025, schools closed and parents withdrew children across a much wider area. UNICEF's 2026 appeal notes that children who are in school face kidnapping risk.

Supply. In some areas there is no school within reach, or no teacher in the school that exists.

Girls face additional barriers in some communities, including early marriage and distance to school where separate facilities are expected.

The almajiri factor

A substantial share of northern out-of-school statistics relates to the almajiri system, which we cover in a separate article. In short: boys sent to study under an itinerant Islamic teacher are receiving an education, but not one that registers in formal enrolment data or that confers accredited qualifications.

Whether they should be counted as "out of school" is a genuine methodological question, and how a given survey treats it affects the total.

What is being done

The National Commission for Almajiri and Out-of-School Children Education was established by Act of Parliament on 27 May 2023, under the Federal Ministry of Education.

Reforms announced on 24 August 2026 in Kaduna set out five pillars — foundational literacy, numeracy, vocational and technical education, digital literacy, and civic education — with states urged to domesticate the Commission's Act and adopt an Accelerated Basic Education Programme. A Nigerian Education Data Infrastructure is planned to track every child, school, teacher and infrastructure gap.

Figures given at that event: a 10-year strategic plan running 2025 to 2035, 119 learning centres established nationwide, and over 700,000 out-of-school children mapped. Kaduna's own project mapped 187,912 children, targeting 100,000 returns, with 25,000 already back in learning.

Set the 119 centres and 700,000 mapped against a population measured in the millions and the scale of the gap is clear.

The funding paradox

Worth reading alongside our article on UBEC. Over ₦65 billion in matching grants sits unclaimed by states, and a further ₦267 billion released but unspent, in a country with the world's largest out-of-school population.

The binding constraint is not entirely money. It is the capacity to convert money into classrooms and teachers.

Frequently asked questions

Which figure should I use? State the range and cite the source and date. 10.2 million (UNICEF, November 2025) and 18.3 million (UNICEF Kano, May 2026) are both attributable.

Is basic education free in Nigeria? Under the Universal Basic Education Act, yes, and compulsory. The associated costs are not free, which is a large part of the problem.

Which states are worst affected? Kano, Katsina and Jigawa account for the largest shares on both bases.
