(a) Four factors that have encouraged the concentration of industries in the Lagos area

• Large market and population: Lagos is the most populous urban area in Nigeria, providing a big ready market for manufactured goods.
• Good port facilities: the harbours at Apapa and Tin Can Island ease the import of raw materials and machinery and the export of finished goods.
• Good transport network: Lagos is the hub of roads, railway and an international airport, linking it to the rest of the country and the world.
• Availability of labour: a large pool of both skilled and unskilled workers is present because of heavy migration to the city.
• Availability of capital and services: banks, insurance and head offices concentrate there, providing finance and business services; electricity and water supply are also relatively better.

(b) Significance of the concentration to the inhabitants

• Provision of employment and steady income for many people.
• Availability of a wide range of manufactured goods to buy locally.
• Growth of allied businesses and services (transport, trading, repairs), spreading wealth.
• Improvement of infrastructure such as roads, power and water in the area.
• However it also brings overcrowding, pollution and high cost of living, which the inhabitants must cope with.
