Table 5.5.6. Real Private Fixed Investment in Equipment and Software by Type, Chained Dollars


1. The quantity index for computers can be used to accurately measure the real growth rate of this component. However, because computers exhibit rapid changes in prices relative to other prices in the economy, the chained-dollar estimates should not be used to measure the component's relative importance or its contribution to the growth rate of more aggregate series; accurate estimates of these contributions are shown in table 5.5.2 and real growth rates are shown in table 5.5.1.
2. Excludes software "embedded,'' or bundled, in computers and other equipment.
3. For 1929-45, includes electrical transmission, distribution, and industrial apparatus (line 18) and electrical equipment, n.e.c. (line 33).
Note. Chained (2000) dollar series are calculated as the product of the chain-type quantity index and the 2000 current-dollar value of the corresponding series, divided by 100. Because the formula for the chain-type quantity indexes uses weights of more than one period, the corresponding chained-dollar estimates are usually not additive. The residual line is the difference between the first line and the sum of the most detailed lines.
n.e.c. Not elsewhere classified
