Types of Industries

Industries are classified by sector: Primary (extracting natural resources — farming, mining, fishing), Secondary (manufacturing — converting raw materials into products), and Tertiary (services — transport, banking, IT, tourism). They are also classified as large-scale vs small-scale, and heavy (bulky raw materials) vs light (small raw materials).

Factors of Industrial Localisation

Eight factors determine where industries are located: raw materials (heavy industries near sources), power/energy, labour (skilled or unskilled), transport (roads, railways, ports), market (near consumers), capital (investment), water supply, and government policy (tax incentives, SEZs). A steel plant locates near iron ore and coal, while a bakery locates near its customers in a city.

World industrial regions include the Ruhr Valley (Germany), Silicon Valley (USA), and Keihin (Japan).
