Tertiary Sector

Supplying to the end consumers that involve banking, global share market, financial services, administration, and other service areas constitute the tertiary sector.

It is one of the prevailing areas of the modern world's advanced market economies where, in the US > 60%, and in the UK >75% of the labor force works in this sector.  The primary, secondary, and tertiary - are the business types involved in the chain of production.

All three are dependent on each other to function efficiently, and under the theory, each job and industry fall into one of the types.

Starting from basic commodities products related to agriculture, extraction of raw material, fishing, logging, animal husbandry, mining, and quarrying that form the primary.

Such sectors provide ways for the economy to gain revenue through exports but the earnings can be volatile.  Manufacturing, processing, constructions, engineering, and energy constitute the secondary.

Globally, the use of machinery has replaced workers and more and more people employed in these two sectors are declining as people are replaced by robots in factories.  

In the US, only 1.8 percent of the labor force was in the primary, and 12.7 percent was working in the secondary (as per 2018 data) sector.
