Product refers to goods and services (including knowledge capturing products) that result from a process of production. Goods are physical, produced objects for which a demand exists, over which ownership rights can be established and whose ownership can be transferred from one institutional unit to another by engaging in transactions on markets. Services are the result of a production activity that changes the conditions of the consuming units, or facilitates the exchange of products or financial assets.

An institutional unit is resident in a country when it has a centre of economic interest in the economic territory of that country. It is said to have a centre of economic interest when there exists some location - dwelling, place of production or other premises - within the economic territory on, or from, which it engages, and intends to continue to engage, in economic activities and transactions on a significant scale either indefinitely or over a finite period of time.
