Japa: Who Is Leaving Nigeria, Who Is Staying, and What Nobody Measures

In short

Nobody knows how many Nigerians have left. There is no exit register, no requirement to report emigration, and no Nigerian agency that publishes a departure count. Every figure you have seen for "how many Nigerians have japa'd" is an estimate built from someone else's data.

What does exist is the receiving countries' visa statistics, and they are good. The UK Home Office, Canada's IRCC, the US State Department and Australia's Home Affairs all publish grants by nationality and route. Those series are the only hard numbers in the conversation, and they measure arrivals into those specific countries through those specific routes, which is a much narrower thing than emigration.

Two patterns are visible in them and both are important. Nigerian movement to the UK and Canada rose steeply through 2022 and 2023, concentrated in the study and health and care worker routes, with dependants making up a very large share. Then both countries tightened: the UK restricted dependants for most taught postgraduate students from January 2024, and Canada capped study permits in the same year. Nigerian grant numbers fell sharply afterwards.

What nobody measures is intent. How many people want to leave, which people, what would change their mind, and what happens to the household they leave behind. That is survey work, it is entirely feasible, and its absence is why the japa conversation is conducted almost entirely through anecdote.

What the word covers, and why that matters

Japa is Yoruba, roughly "to run" or "to flee", and it moved into general Nigerian usage around 2021 and 2022 as shorthand for emigrating.

The breadth of the word is the first measurement problem. It is used for all of the following, which have almost nothing in common:

• a graduate doing a taught master's abroad with the intention of staying
• a nurse recruited directly into a health system overseas
• a software engineer taking a remote job and relocating
• a family emigrating through a skilled-worker programme
• a student leaving with no intention of returning
• a trader moving within West Africa
• an irregular migration attempt across the Sahara and Mediterranean
• a professional moving for three years and planning to come back

These are different decisions, taken by different people, with different consequences for Nigeria. A single number covering all of them would not be informative even if it existed, which is a reason to be suspicious of anyone who offers one.

The only hard numbers: receiving-country visa data

The useful discipline is to say precisely what each source measures.

UK Home Office immigration statistics. Quarterly, by nationality and visa route: study, skilled worker, health and care worker, family, visitor. Also publishes dependants separately from main applicants, which turns out to be the most revealing part of the Nigerian series.

Immigration, Refugees and Citizenship Canada. Study permits, work permits and permanent residence admissions by country of citizenship, with the Express Entry and provincial nominee streams broken out.

US State Department. Non-immigrant visa issuances by nationality and class, plus immigrant visa statistics and the Diversity Visa results.

Australian Department of Home Affairs. Visa grants by stream and nationality.

Nigerian sources. The Nigeria Immigration Service publishes passport and travel-document activity, and the Nigerians in Diaspora Commission has a remit covering the diaspora. Neither publishes anything that functions as an emigration count.

Remittance data. The Central Bank of Nigeria and the World Bank publish remittance inflows. They are a real signal about diaspora size and economic connection, and they are not a headcount, because remittance behaviour varies enormously by destination, income and how long someone has been away.

What the numbers show

Two things, stated at the level the data supports.

The 2022 to 2023 surge was concentrated and dependant-heavy. Nigerian grants in the UK study and health and care worker routes rose sharply, and in both routes dependants formed an unusually large share of the total compared with most other nationalities. That tells you something important about who was moving: not individuals testing an opportunity but households relocating.

The 2024 tightening worked, quickly. The UK's restriction on dependants for most taught postgraduate courses, effective January 2024, and Canada's study permit cap in the same year, were followed by steep falls in Nigerian grant numbers. Whichever view you take of the policies, the responsiveness is the finding: the flow was highly sensitive to the rules at the receiving end.

That second point is the one most commentary misses. Japa is usually discussed as though it were driven entirely by Nigerian conditions. The volume data suggests it is driven at least as much by what the destinations allow, and Nigerian conditions set how many people want to go rather than how many get to.

Health workers, specifically

The health workforce is the one area where the outflow is well enough documented to say something firm, because receiving-country professional registers record it.

Nursing and midwifery regulators in the UK and elsewhere publish the countries where registrants trained, and Nigerian-trained nurses have been among the fastest-growing groups on those registers. Medical registers show a similar direction. This is more reliable than general migration data because registration is a precondition of practising, so the count is close to complete for that profession in that country.

The policy context is worth knowing. The World Health Organization maintains a health workforce support and safeguards list of countries facing the most pressing health workforce challenges, and Nigeria has been included on it. Inclusion signals that active international recruitment from that country should be subject to safeguards rather than pursued freely. It has not stopped individual professionals from applying, which is a different thing from being recruited, and the distinction is central to the ethics of the debate.

What remains unmeasured even here: how many return, how many are working below their qualification level, what happens to the facilities they left, and whether the remittances flowing back offset the service loss. Those are the questions that determine whether health worker migration is a net loss to Nigeria or a more complicated bargain, and none of them is settled with Nigerian data.

The education link

This is where the japa question stops being a migration story and becomes an education story.

A very large share of the measurable outflow moves through the study route. That means the decision is made at a point in the education system, by people choosing between a Nigerian institution and a foreign one, and it is influenced by information about both.

Which produces a set of questions that are commercially and socially significant and almost entirely unanswered:

• At what stage is the decision made? Secondary school, during a first degree, or after some years of work?
• What is the comparison set? Which Nigerian institutions did the family consider, and against which foreign ones?
• What drives the choice? Quality, strike risk, credential portability, the immigration pathway attached, or the cost after exchange rates?
• Who pays? Family savings, asset sales, diaspora relatives, or loans, and at what cost?
• How much of the intent is about the degree and how much about the visa? A study route used primarily as a migration route is a different market from one used primarily for education, and the two respond to different things.
• What would retain them? This is the question with policy value and the one nobody asks, because asking it requires offering realistic alternatives rather than exhortation.

These sit directly on top of the data the Nigerian school and higher education sector already generates about choice, fees and outcomes. Combining enrolment and school-choice data with emigration intent is one of the few genuinely novel datasets available in this market, and the reason it does not exist is that the two halves are held by people who do not talk to each other.

What nobody is measuring

A consolidated list.

• Stated intent. What share of Nigerians intend to emigrate, with a defined time frame and a seriousness filter, because "would you like to live abroad" is close to universal and therefore useless. The useful question is what they have actually done about it: a passport obtained, an exam taken, an application filed, money set aside.
• Who, specifically. Intent by age, education, sector, income and state. The policy implication is completely different if intent is concentrated among final-year students in two zones versus spread evenly.
• The trigger. Not a list of reasons to agree with, which produces a ranking of grievances, but the specific event that moved someone from thinking about it to acting.
• The retention question. What concretely would change the decision, tested against realistic options rather than hypotheticals.
• Return intent and actual return. How many plan to come back, on what timeline, under what conditions, and how many actually do. Return is almost entirely invisible in the data and may be a larger flow than anyone assumes.
• Household effects. What happens to the household left behind: income, childcare, elder care, business continuity, school changes. This is where the social cost sits and it is unrecorded.
• The cost of the attempt. What families spent on applications, exams, agents and tuition deposits, including for attempts that failed. Failed attempts are invisible in every dataset and are a real transfer out of Nigerian households.
• Agent and intermediary conduct. A large, largely unregulated industry sits between the aspiration and the application, and nobody has measured what it charges or how often it delivers.

Every one of these is a survey question. None requires access to anything confidential. They are absent because no one has paid for them.

How to read a japa claim

Does the figure measure departures or arrivals? Almost every credible number is a receiving-country arrival count for one route into one country. Presented as a Nigerian emigration total, it is wrong by construction.

Does it count dependants? Main applicants and total grants can differ substantially for Nigerian routes, and quoting one as the other changes the picture materially.

What period, and which side of the 2024 rule changes? A 2023 figure described in the present tense is describing a regime that no longer exists.

Is it intent or behaviour? "X% of Nigerian youth want to leave" and "X% have applied" are different claims with different consequences, and the first number is always much larger.

If a survey is cited, who was sampled? An online survey about emigration intent reaches people with reliable internet and, disproportionately, those already planning to go. That is the single most common flaw in japa research and it inflates every estimate.

Is return accounted for? Net movement is the policy-relevant quantity and gross departures is the number that gets published.

What a proper study looks like

1. A nationally representative sample, reached across multiple modes so that respondents without reliable internet are included, because an online-only study of emigration intent is biased in the direction of its own conclusion.
2. Behavioural intent measures, not attitudinal ones. Passport held, exams sat, applications filed, money set aside, agent engaged, with dates. These are checkable, specific and far harder to overstate than a sentiment question.
3. Sized for the breakdowns that matter, meaning by zone, by age band and by education level, because the national figure is the least interesting output.
4. A trigger and retention module, asking what moved the decision and what would change it, tested against concrete alternatives.
5. A household module covering those left behind, which requires sampling households rather than only individuals.
6. A returnee component, because return is the invisible half of the story.
7. Repeated on a fixed cadence, since the 2024 policy response showed how fast this flow changes, and a single wave would have missed it entirely.
8. Published questionnaire and base sizes, so that a newsroom or a ministry quoting the number can defend it.

That study would produce the first real Nigerian figure on the subject, and every number in it would be citable because the method would be public. Where NigeriaPolls publishes on emigration intent, the questionnaire and the base sizes go out with the findings.

Frequently asked questions

How many Nigerians have emigrated?

Nobody knows. Nigeria has no exit register, no requirement to report emigration and no agency that publishes a departure count, so every total in circulation is an estimate built from other countries' data. The reliable figures are receiving-country visa statistics from the UK Home Office, Canada's IRCC, the US State Department and Australia's Home Affairs, and each measures arrivals into one country through one route rather than Nigerian emigration overall.

What does japa mean?

Japa is Yoruba, roughly "to run" or "to flee", and it entered general Nigerian usage around 2021 and 2022 as shorthand for emigrating. Its breadth is a measurement problem: it covers postgraduate students, directly recruited nurses, remote workers relocating, families on skilled-worker programmes, traders moving within West Africa and irregular migration attempts, which are completely different decisions with different consequences.

Where can I find reliable data on Nigerian emigration?

Receiving-country sources. The UK Home Office publishes quarterly grants by nationality and route with dependants listed separately. Canada's IRCC publishes study permits, work permits and permanent residence admissions by citizenship. The US State Department publishes visa issuances by nationality and class. Australia's Home Affairs publishes grants by stream. On the Nigerian side, the Immigration Service publishes travel-document activity and the Central Bank publishes remittance inflows, but neither functions as an emigration count.

Why did Nigerian student visa numbers to the UK and Canada fall in 2024?

Because both countries tightened the rules. The UK restricted dependants for most taught postgraduate students from January 2024, and Canada introduced a cap on study permits in the same year. Nigerian grant numbers fell steeply afterwards in both cases. The speed of that response is itself the finding: the flow was highly sensitive to receiving-country policy, which means japa volumes are set at least as much by what destinations allow as by Nigerian conditions.

Is Nigeria losing its health workers?

The health workforce is the one area where the outflow is well documented, because receiving-country professional registers record where registrants trained, and Nigerian-trained nurses have been among the fastest-growing groups on them. The World Health Organization has included Nigeria on its health workforce support and safeguards list, which signals that active international recruitment should be subject to safeguards. What remains unmeasured is how many return, how many work below their qualification level, what happened at the facilities they left, and whether remittances offset the service loss.

What is the connection between japa and Nigerian education?

A very large share of the measurable outflow moves through the study route, which means the decision is taken inside the education system by families comparing Nigerian institutions with foreign ones. What is not known is at what stage the decision is made, which Nigerian institutions were in the comparison set, whether the driver is academic quality or the immigration pathway attached to the course, who pays and at what cost, and what would actually retain a student. Combining school-choice data with emigration intent would be one of the few genuinely new datasets available in this market.

What percentage of Nigerians want to leave the country?

Any specific figure you see for this should be treated carefully, because the answer depends almost entirely on how the question was asked and who was asked. "Would you like to live abroad" returns near-universal agreement and measures nothing. Useful measurement asks what someone has actually done: obtained a passport, sat an exam, filed an application, set money aside, engaged an agent. Online-only surveys on this topic also over-sample people already planning to leave, which inflates every published estimate.

What is not known about japa?

Most of what matters. Stated intent with a seriousness filter and a time frame; who specifically intends to go, by age, sector, education and state; the trigger event that moved someone from considering to acting; what would concretely change the decision; return intent and actual return, which is the invisible half of the story; the effects on households left behind; the money families spent on attempts that failed; and the conduct of the large, largely unregulated agent industry sitting between the aspiration and the application.
