(a) Relative Importance Weight (Contribution to the total industrial production index): Primary metal: Primary smelting and refining of copper (DISCONTINUED), Percent, Seasonally Adjusted (RIWG331411S)
The IP proportions (typically shown in the first column of the relevant tables in the G.17 release) are estimates of the industries' relative contributions to overall growth in the following year. For example, the relative importance weight of the motor vehicles and parts industry is about 6 percent. If output in this industry increased 10 percent in a month, then this gain would boost growth in total IP by 6/10 percentage point (0.06 x 10% = 0.6%).

NAICS = 331411
