Definition: Quantity relative

SNA 1993

A quantity relative is the ratio of the quantity of a specific product in one period to the quantity of the same product in some other period.

A very similar definition is applied in the Consumer Price Index Manual (2004):

The ratio of the quantity of a product in one period to the quantity of that same product in some other period. http://ec.europa.eu/eurostat/ramon/statmanuals/files/SNA_1993_EN.pdf ILO, IMF, OECD, Eurostat, UNECE, World Bank, Consumer Price Index Manual: Theory and Practice, 2004
