household consumption consists of expenditures by resident households, and by nonprofit institutions that serve households, on goods and services that are consumed by individuals. This includes consumption of both domestically produced and foreign goods and services.
government consumption consists of government expenditures on goods and services. These figures exclude government transfer payments, such as interest on debt, unemployment, and social security, since such payments are not made in exchange for goods and services supplied.
investment in fixed capital consists of total business spending on fixed assets, such as factories, machinery, equipment, dwellings, and inventories of raw materials, which provide the basis for future production.

Earlier editions of The World Factbook referred to this concept as Investment (gross fixed) and that data now have been moved to this new field.

This figure may be positive or negative. If the stock of unsold output increases during the relevant time period, investment in inventories is positive, but, if the stock of unsold goods declines, it will be negative. Investment in inventories normally is an early indicator of the state of the economy. If the stock of unsold items increases unexpectedly – because people stop buying - the economy may be entering a recession; but if the stock of unsold items falls - and goods "go flying off the shelves" - businesses normally try to replace those stocks, and the economy is likely to accelerate.
