Chained-dollar estimates

Inflation-adjusted estimates that are prepared to supplement the chain- type quantity indexes. In general, the chained-dollar estimates are calculated by multiplying the current-dollar value of an aggregateor component for the reference year by its corresponding chain-type quantity index and then dividing by 100. These estimates are denominated in units of the dollars of the reference year. The chained- dollar estimates may be used to calculate growth rates (which will be identical to those calculated using the quantity indexes), but because these estimates are not additive for periods other than the referenceyear, they should not be used to calculate component shares of an aggregateor to calculate component contributions to the growth of an aggregate.
