Lagos has two industrial layers. The formal-sector layer — the multinational FMCG plants at Ikeja, Apapa and Ilupeju, and the petrochemical/refining infrastructure at Lagos-Ibafo — is well-documented and largely foreign-owned. The other layer — the Mushin–Ladipo–Idumota–Aspamda–Alaba–Computer Village belt — is Nigerian-owned, almost entirely informal, and produces a quantum of economic activity that does not appear in any official manufacturing statistic but without which Lagos as a city would stop functioning.
Five sub-clusters compose the informal Lagos belt:
- Computer Village (Otigba, Ikeja). Roughly 4,000 shops trading and repairing phones, laptops, peripherals and accessories. Daily turnover estimated at ₦15-20 billion (~$10-13m at 2024 rates). The single largest concentration of small-scale electronics trading in West Africa. The cluster does almost no original manufacturing — it imports, refurbishes, repairs and configures — but the repair and refurbishment workshops are arguably West Africa's largest practical electronics-technician training pipeline.
- Ladipo (Mushin). The largest used-auto-parts market in West Africa. An estimated 12,000 shops dismantling, sorting and redistributing used-car components — primarily for the tokunbo vehicles that compose 70%+ of Nigerian road traffic. The cluster sustains a downstream network of mechanic workshops across every Nigerian city.
- Idumota and Balogun (Lagos Island). The wholesale distribution layer for textiles, ready-to-wear, cosmetics, perfumes and household items entering Lagos through Apapa and Tin Can. Idumota is the Lagos answer to Onitsha Main Market — same arbitrage-based business model, same family-firm ownership, same informal credit and security arrangements.
- Alaba International Market (Ojo). The largest electronics-wholesale and home-appliance market in West Africa, and the original distribution channel for the Nollywood VCD economy (see Nollywood). The Alaba traders financed much of the 1990s–2000s Nollywood production through the marketer system.
- Aspamda (Trade Fair Complex, Lagos-Badagry corridor). Mixed wholesale and assembly cluster covering everything from generator parts to plastic crockery. Less iconic than Idumota or Alaba but commercially comparable in throughput.
What ties these five sub-clusters together is the Lagos consumer market, the Apapa-Tin Can port system that supplies their inventory, and the diaspora-Lagos remittance flow that finances much of the working capital. Unlike Nnewi or Aba, the Lagos informal belt does not have a single dominant ethnic apprenticeship system; ownership is mixed (Yoruba traders in Idumota, Igbo traders in Alaba and Ladipo, a mix at Computer Village), and capital-formation runs through a variety of channels (Yoruba ajo, Igbo Igba-Boi, family pooling, BDC dollar facilities).
The binding constraint on the Lagos informal belt is port and traffic dysfunction. Apapa truck-turnaround that should take hours takes days; the Apapa-Oshodi-Ladipo trucking corridor has been the single largest source of operational loss in Lagos trading since the early 2010s. The Lekki Deep Sea Port and the Lekki–Epe industrial corridor are the structural attempt to relocate the Lagos consumer-import system away from Apapa; whether they re-route the informal belt or simply create a parallel formal corridor is the open question of 2025–2030.
For the series, the Lagos informal belt is the proof that the unsubsidised pattern works at urban scale and across multiple sub-clusters within a single city — provided the cultural infrastructure (trader apprenticeship, market-authority governance, informal credit) is in place.

Six industrial clusters: where the unrecorded economy actually makes things
Nigeria's industrial base did not die; it migrated. From Nnewi auto-parts to Aba shoes to Kano tanneries, these clusters now out-produce most state-owned plants ever did.
