Where this fits. This is the post-2015 wave-only snapshot. The full four-decade history — Andrew, SAP, the 1990s medical drain, EndSARS japa, the 2023 visa-rejection era — is at The Andrew Generation — Japa from 1986 to 2024.
Nigerian emigration is not new. The 1980s SAP-era brain drain to Saudi Arabia, the United States and the UK — economists, engineers, doctors and academics — was extensively documented (the 1986 IMF Working Paper on Nigerian emigration estimated that one in three of the country's PhD-holders had left by 1985). What is new about the post-2015 Japa wave is its scale, its institutional formality (most movement is through legal study-permit and skilled-worker visa channels rather than informal migration), and the speed at which it has hollowed out specific professions.
The headline numbers:
- UK General Medical Council Register: Nigerian-trained doctors registered in the UK rose from 4,765 in 2015 to over 12,000 by 2024 — Nigeria is now the third-largest source country of UK doctors after India and Pakistan.
- UK Nursing and Midwifery Council Register: Nigerian nurses registered in the UK rose from 2,400 in 2017 to over 18,000 by 2024 — the single fastest-growing source country.
- Canadian Study Permits issued to Nigerians: 3,920 in 2015; 47,125 in 2023 — a twelve-fold increase, making Nigeria the second-largest source of international students in Canada.
- US Diversity Visa Lottery: Nigeria temporarily disqualified in 2020–2022 over high-issuance rates; reinstated 2023.
- MTN Foundation / Jobberman / Stears 2023 Survey of Lagos tech professionals: 56 percent of respondents had concrete plans to emigrate within 18 months.
The sector-by-sector picture is sharpest in healthcare. The Medical and Dental Council of Nigeria's register holds about 100,000 doctors nationally; the Nigerian Medical Association estimates that at most 30,000 are actively practising in Nigeria, and that over 1,000 doctors emigrate each year. The Federal Government's 2023 'Nigerian Medical Council Examinations' verification surge — the document required for UK GMC registration — set new monthly records throughout 2023 and 2024.
The tech-sector picture is less catastrophic because the tech labour force is younger, smaller, and more globally networked. The 2020–2022 remote-work boom (Andela, Big Cabal, Flutterwave, Paystack post-Stripe-acquisition) showed that Nigerian tech workers could earn dollar incomes without physical emigration. The 2023–2024 layoffs at major US tech companies somewhat slowed the tech-sector exodus.
The driver picture is consistent across sectors: cost-of-living shocks (see Naira devaluations and Fuel subsidy), security concerns (see Boko Haram, Herder-farmer conflict, Unknown gunmen), and education-system breakdown (see ASUU Strikes Register). The political response — the 2023 establishment of the Federal Ministry of Youth and the 'Renewed Hope Agenda' youth-jobs programme — has been modest relative to the scale of the outflow.
The diaspora remittance side of the equation: Nigerians abroad remitted an estimated $24.3 billion home in 2023 (World Bank), making Nigeria the largest remittance recipient in Africa and the sixth-largest in the world. Whether the remittance flow compensates for the human-capital outflow is the central economic debate of the Japa decade.

The Andrew of 1986 never had this many doors. The 2022–23 UK student-and-dependant pipeline alone moved a quarter of a million Nigerians out in eighteen months.
