Industrial locations are complex in nature. They are influenced by both physical and human factors. Three important factors that influence the location of industries in a region are as follows : (i) Availability of raw material — Raw materials required for the industry must be available cheaply and at close range or at well-linked places. In case of industries using bulky raw material like iron, bauxite, etc., the ideal location is near the raw material sources. (ii) Power resources — Power, energy or fuel is essential for the working of any industry. They are required for running the machines and as fuel in smelters in case of mineral based industry. So, power resources like coal and electricity must be available in abundance in the vicinity where an industry is located. (iii) Market — The goods produced must have a market for their sale. The market influences the demand as well as type of goods produced in a region. For example, cold regions like Jammu and Kashmir will have requirement for woollen garments. So woollen textiles will be located in that region. Consumer goods industries and automobile industries are located near big towns and cities.
