Answer & Enrich Your Learning:

Foot loose industries:

  • Footloose industry is a general term for an industry that can be placed and located at any locationwithout effect from factors such as resources or transport.
  • Foot loose industries can be located in a wide variety of places. They are not dependent on any specific raw material, weight losing or otherwise.
  • They largely depend on component parts which can be obtained anywhere. They produce in small quantity and also employ a small labour force. These are generally not polluting industries.
  • In India, the important factor in their location is accessibility by road network.


  • Land on the edge of cities is often cheaper than in the centre. The out of town surroundings and easy access to workers in the suburbs provides an ideal location for building science and business parks.
  • Motorway links and railways also provide access for commuters and for transporting components and products.


  • Workers wanting to live near their place of work increases the demand for housing and puts pressure on green belt land.
  • As demand grows, house prices increase. This means that less skilled and lower paid workers are priced out of the market in desirable areas.
