Industrial Production and Capacity Utilization - G.17

Text Data Files

The files containing data from 1986 to present are updated each month as part of the G.17 release process. The historical data, grouped by the table in which they appear in the G.17 release, are available in text files. The format for each line in the files consists of an industry code, a year, and 12 months of data (to four decimal places) when available. The data have various start dates; the earliest is 1919.

Current and Historical Data: Relative Importance Weights

Data:

Documentation: These files include descriptions and the codes that represent the industrial production series in Tables 1 and 2.

The relative importance weights provided in the data file allow the user to compute special aggregates of industrial production that are not published in the G.17 release. These weights should be used to combine growth rates of component IP series to obtain a growth rate for a special aggregate.

If industry C is industries A and B combined, the growth of IP for C can be approximately computed using the following formula, where IP_A[t] is the level of IP for industry A in month t and RIW_A[t-1] is the relative importance weight of industry A in month t-1.

IP_C[t]/IP_C[t-1] = (RIW_A[t-1]*IP_A[t]/IP_A[t-1] + RIW_B[t-1]*IP_B[t]/IP_B[t-1])/(RIW_A[t-1] + RIW_B[t-1])

To exclude industry B from IP aggregate A, one would subtract instead of adding:

IP_C[t]/IP_C[t-1] = (RIW_A[t-1]*IP_A[t]/IP_A[t-1] - RIW_B[t-1]*IP_B[t]/IP_B[t-1])/(RIW_A[t-1] - RIW_B[t-1])
