Sector It is a concept with multiple meanings. In the economy , a sector is a set of productive or commercial activities. All these groups, on the other hand, can congregate in three broad sectors: primary sector , secondary sector and third sector .

He third sector It is also known as service sector , since it includes those activities that do not involve the production of material goods. Companies in the tertiary sector, in this way, are dedicated to the satisfaction of different needs of the people .

It is often said that the tertiary sector is dedicated to the organization and distribution of what the other two sectors produce: primary sector (focused on the direct extraction of natural resources) and the secondary sector (oriented to the transformation of natural resources through industrial processes).

Specifically, we can establish that the tertiary sector is made up of several areas such as these:
1-Financial activities, which would be all related to banks, the stock market, insurance ...
2-Activities that become services that are provided to companies: advice, administration, management, consulting ...
3-Tourism and hospitality.
4-Activities in transport and communication.
5-Area of ​​telecommunications, where the services related to telephony would have special prominence.
6-Commercial activity, whether at retail, wholesale, franchisees ...
7-Personal services that aim to improve the quality of life of citizens. In this section, you can include both activities related to aesthetics (hairdressing, makeup ...) and what would be the welfare state (schools, hospitals, administration ...).
8-Activities in terms of function and public administration: justice, defense, political representation ...
9-Services related to what is leisure and culture: cinema, theater, music, sport ...
10-Media, whether written, digital, television or radio.
11-Activities related to Information Technology such as Internet.

All economic sectors are considered to be fundamental for the good development of a country. However, the tertiary, in particular, brings a number of notable advantages, such as these:
-Its transport activities allow not only to grow cities but also to attract tourism and improve communications within the country.
-The ICT, for example, have given a radical change to the world of work since they have allowed the creation of new jobs and new professions, has led to the existence of work from home ...

A Supermarket , for example, is part of the tertiary sector. This type of stores does not obtain the resources it sells from the nature nor does it process them, but acquires the products of the primary and secondary sectors and sells them to the final consumer.

The transport companies , the schools , the TV channels , the health clinics , the telephone companies and the banks They are other actors in the tertiary sector. As you can see, this sector is made up of entities with very different characteristics from each other, but which coincide in not dedicating themselves to the extraction of natural resources directly or to industrial processes.

Some tertiary sector activities are sometimes included in a quaternary sector or in a quinary sector , although the most popular economic theory refers only to three sectors.
