Primary industries are found where the resources are found eg. coal mines have to be found on coal fields.
The location of manufacturing industry is influenced by the following factors
- labour supply - how easy it is to get workers
- transport - by road, rail, sea and air to move goods and workers
- site - is the land flat, dry and with room for expansion
- raw materials - being near to heavy, bulky raw materials will help reduce transport costs
- market - being close to customers also reduces transport costs
- power supply - most modern industry uses electricity
- government aid - are grants, loans, training or other kinds of help available for a site
Market and labour supply are very important in service industries.
Quaternary industries are less tied down to a particular location.
