Outline the role of industrialization in the economic development of Nigeria.

Industrialization is the process of building and expanding manufacturing and processing industries in an economy. For a developing country like Nigeria, it is central to structural change and economic development. Its roles include:

1. Employment creation. Industries employ large numbers of skilled and unskilled workers, reducing unemployment and raising incomes.
2. Diversification of the economy. Manufacturing reduces Nigeria's over-dependence on the export of crude oil and primary products, making the economy more balanced and stable.
3. Increase in national income and GDP. Industrial output adds value to raw materials and raises total production, increasing per capita income and standards of living.
4. Provision of goods and reduction of imports. Local manufacture of consumer and capital goods reduces dependence on imports, saving foreign exchange and improving the balance of payments.
5. Earning of foreign exchange. Exporting manufactured (processed) goods earns more foreign exchange than exporting raw materials.
6. Development of infrastructure and technology. Industrial growth encourages the building of roads, power and communications and promotes the acquisition of modern skills and technology.
7. Growth of related sectors. Industries create linkages that stimulate agriculture (raw materials), commerce and services.

Examination reminder: tie each point to development (higher incomes, diversification, technology), not merely to production.
