Economy segment

An economy segment is an area of the economy.

Classifications

Two major conventional classifications divide enterprises in:

Three groups, the public sector, private sector, and nonprofit sector, depending on their ownership.
Three or four groups, the primary sector, secondary sector, tertiary sector, and, optionally, quaternary sector, in which enterprises are grouped based on a type of produced market exchangeables. This classification also fits into economic phases of precedence, since lower levels of the economy emerged before higher levels and higher levels depend on lower ones. However, every enterprise usually produces some mix of products, so it can belong to several segments.

Both classifications use the same term, sector. Neither of the classifications takes single households into account.
