This figure illustrates the percentages of a country's economy made up by different sectors. The figure illustrates that countries with higher levels of socio-economic development tend to have proportionally less of their economies operating in the primary and secondary sectors and more emphasis on the tertiary sector. The less developed countries exhibit the inverse pattern.
Three sectors according to Fourastié
Clark's sector model

One classical breakdown of economic activity distinguishes three sectors:[1]

In the 20th century, economists began to suggest that traditional tertiary services could be further distinguished from "quaternary" and quinary service sectors. Economic activity in the hypothetical quaternary sector comprises information- and knowledge-based services, while quinary services include industry related to human services and hospitality.[2]

Historic evolution

An economy may include several sectors (also called "industries") that evolved in successive phases:

Even in modern times, developing countries tend to rely more on the first two sectors, in contrast to developed countries.

By ownership

An economy can also be divided along different lines:

Regarding the terminology itself Clark informs that "the term tertiary industries was originated by Professor A. G. B. Fisher in New Zealand, and became widely known through the publication of his book, The Clash of Progress and Security, in 1935. It took its origin from the titles current in Australia and New Zealand of 'primary industry' for agriculture, grazing, trapping, forestry, fishing and mining, and 'secondary industry' for manufacture. In Australia and New Zealand these terms are not only used in statistical reference books but are widely current in popular discussion. The phrase 'tertiary industries' therefore immediately carries, in these countries, a suggestion of those excluded by the official definition of 'secondary industries."
