In business, the business sector or corporate sector - sometimes popularly called simply "business" - is "the part of the economy made up by companies".[need quotation to verify] It is a subset of the domestic economy, excluding the economic activities of general government, of private households, and of non-profit organizations serving individuals. An alternative analysis of economies, the three-sector theory, subdivides them into:
- the primary sector (producing raw materials)
- the secondary sector (carrying out manufacturing)
- the tertiary sector (providing sales and services)

In the United States the business sector accounted for about 78 percent of the value of gross domestic product (GDP) as of 2000[update]. Kuwait and Tuvalu each had business sectors accounting for less than 40% of GDP as of 2015[update].
The Oxford English Dictionary records the phrase "business sector" in the general sense from 1934. Word usage suggests that the concept of a "business sector" came into wider use after 1940. Related terms in previous times included "merchant class" and "merchant caste".
