CHAINED INDEX WEIGHTING

Statistics Directorate    
Definition:
Chained index weighting is an alternative way of weighting together the subaggregates that form GDP. The key difference to the fixed-weight aggregation, used in most countries, is that the prices are continuously updated and that "substitution bias" is avoided and that measures are independent of the choice of base year.
