The industry is an economic activity responsible for delivering us valuable finished goods that we use in our daily lives. For example, even the smallest of things, a pencil or paper has to go through more than one type of industry to develop into a finished product. Read below to know more about the classification and significance of industries.

1. Importance of Manufacturing 

i. Industries add value to raw materials and turn them into usable finished products.

ii. Industries help to modernize the primary sector as it assists in creating jobs in the secondary and tertiary sectors. 

iii. It reduces poverty and unemployment rates. 

iv. Manufacturing industries boost trade and commerce, which brings in foreign exchange.

v. It contributes to the progress of the country by improving the economy.

2. Location 

The location of an industry is affected by the availability of several things—

a. Capital: How much capital can be gained after investment and how much capital will be required to sustain the business in the location - all of these factors determine the location which will require the least capital, most favourable for industrial development. 

b. Raw Material: If the location has raw materials easily available, it is ideal for the industries as raw materials form the backbone of any industry. 

c. Market: The location should have a booming market nearby so the industries can sell their products easily. These markets should have both national and international connections.

d. Government Policies: The government-made rules and regulations regarding imports, exports, and other traffic also determine the location of an industry. 

e. Power: This refers to the availability of electricity in that location. Power is essential for industrial machinery to function and produce goods. Uninterrupted power increases the productivity of the factory. 

f. Labour: Cheap labour should be readily available to work in the industry. The workforce is necessary to operate its machines and also to oversee the administrative work. 

3. Classification of Industries 

i. There are several grounds on which industries are classified. 

ii. Based on raw materials, industries can be classified into the following types:

a. Agro-Based Industries: Here plant and animal-based products serve as raw materials to produce finished products. For instance, food processing, dairy products, vegetable oil, cotton textile industries, etc. 

b. Mineral-Based Industries: These primary industries involve the usage of ores of various minerals as their raw materials. Finished goods from these industries are used as raw materials for other industries. For instance, iron, an outcome of mineral-based industry, is used to make heavy machinery, tools, etc. 

c. Marine-Based Industries: These industries use products obtained from the oceans and seas as raw materials. For instance, industries that process seafood or manufacture fish oil. 

d. Forest-Based Industries: These are industries employing forest produce as raw material. For instance, pulp and paper, pharmaceuticals, furniture industries. 

iii. Based on capital investment, industries are of the following types:

a. Small Scale Industries: These are industries using a lesser amount of capital and technology. For example, silk weaving and food processing industries. 

b. Large Scale Industries: These are industries involved in the production of large volumes of products as the investment of capital is higher and the technology used is superior. For example, automobiles production and heavy machinery industries. 

iv. Based on ownership, industries are of the following types:

a. Public Sector Industries: These are industries that are owned as well as operated by the government. For example, Hindustan Aeronautics Limited.

b. Private Sector Industries: These are industries that have individuals or a group of individuals owning and operating them. For example, ITC Limited and Reliance Industries Limited. 

c. Joint Sector Industries: These are industries owned and operated both by the state and individuals or a group of individuals. For example, Maruti Udyog Limited. 

d. Cooperative Sector Industries: These are industries that are under the ownership and operation of producers or suppliers of raw materials, workers, or both. For example, AMUL, Sudha Dairy, etc. 

4. Agro-Based Industries 

i. Textile Industry: It is the only industry in India, which is both self-reliant and thorough in the value chain. It generates employment, industrial production, and foreign exchange. 

a. Cotton Textiles: It links workers who work in weaving, designing, ginning, packaging, spinning, sewing, tailoring, and cotton ball plucking and agriculture. Until the industrial revolution took place, cotton cloth was made from looms or hand spinning wheels. The USA, China, India, and Japan are the most crucial cotton-producing countries. It was the year 1854 when in Mumbai the first successful mechanized cotton mill was established.

b. Jute Textiles: The largest manufacturer of jute goods and raw jute is none other than our country India. Several mills are located in West Bengal, mainly along the banks of the Hugli river. Most importantly, jute was employed for making textiles in the Indus valley civilization since the third millennium BC. 

ii. Sugar Industry: India is the world's second producer of sugar. The sugar industry includes certain stages like the production of sugars, their processing, and finally marketing. This industry is seasonal in nature.

5. Mineral-Based Industry 

i. Iron and Steel Industry: Heavy, medium, and light industries depend on the iron and steel industry for primary machinery. Bhilai ( Chhattisgarh), Jamshedpur ( Jharkhand), Burnpur (West Bengal) are some hotspots locations for the iron and steel industry. TISCO or Tata Steel Company Limited is an important example of such an industry. 

ii. Aluminum: Smelting Bauxite is the raw material employed in this industry. It is the second-most crucial metallurgical industry in India and has immensely gained popularity.

Overview of Industries

There are so many different types of industries that surround us these days. People try to classify industries on the basis of raw material and so much more. Not to mention that these industries have certain standards and sizes as well. So, the entire classification is really important. But before that, learning about the process of manufacturing in these industries is important. There are several machines at work that help in the transformation of raw materials into goods and products. For example, the pulp from the tree is changed into paper and then is transformed into a notebook. There are two different stages at play here. Students can easily learn how to classify industries on the basis of ownership from this.

To define the term ‘industry’, we can say that it is basically the economic activities that take place when it comes to the extraction of materials and production of goods along with some other services as well. Class 8 Geography Chapter 5 also discusses the classification of industries. We are going to provide some examples to make you understand what the industries do. There is the iron and steel industry which tends to help in the production of goods. Also, there is the coal mining industry that helps in the extraction process of coal. The tourism and hospitality industry, on the other hand, is completely service-based.

Classification of Several Industries

We have found that industries can be classified on three different points. We are going to mention these points to you so that you can understand.

1. On the Basis of Size: The classification of industries on the basis of size would mean that the industries would measure the capital and also the number of employees with respect to the production. When it comes to the classification of industries on the basis of size in India, there are 2 types. These are the small-scale and large-scale industries.

  • Small-Scale: Small scale industries are the ones which tend to use less capital amount and do not take advantage of more technologically advanced options. Hence, the production of goods is also on a small scale. Such industries do not require many employees for the production of goods as well. The best examples of a small-scale industry include food processing and silk weaving.

  • Large-Scale: The large scale industries are the ones which tend to produce the goods on a larger scale and volume. Hence, the capital investments in these types of industries would definitely be a lot higher for sure. Not to mention that the technology which is used will be very superior when it comes to large-scale industries. Some of the examples of the large-scale industries would be the automobile industries and also heavy machinery.

2. On the Basis of Raw Materials: The classification of industries on the basis of raw material is one of the most important forms of classification. There are different types of industries that fall under this category such as mineral-based, agro-based and marine-based industries.

  • Mineral Based: These primarily produce minerals by using ores as their raw materials. The products manufactured from these industries feed the others.

  • Marine Based: These industries tend to use different products from oceans and seas as raw materials. Production of seafood along with fish oil can be one of the examples.

  • Agro-Based: These industries tend to have some role to play in food processing, cotton textile manufacturing, vegetable oil production and other products.

  • Forest-Based: These industries tend to use the different resources of the forest for raw materials such as paper, furniture, pharmaceuticals, etc.

3. On the Basis of Ownership: To classify industry on the basis of ownership would divide the industries into two groups namely Private Sector industries and the Public Sector industries.

  • Private Sector: These industries are the ones which are owned as well as operated by a single individual or more than one individual.

  • Public Sector: These industries have governments owning and operating them.

  • Cooperative Sector: These are the industries which have suppliers and producers for the raw materials that own the industry.
