For example, if the price doubles in two years versus its base, the index figure after two years will be 200.0. The advantage of adopting an index methodology is that numerous diverse items can all be assigned the same starting value (e.g. January 2000 = 100.0) to determine how they perform relative to each other over time.
Crushed stone was the leading nonfuel mineral commodity in 2019 accounting for 22% of the total value of U.S. nonfuel mineral production. Increased construction activity resulted in increased prices and production of some industrial minerals. In 2018, as a result of U.S. Department of Commerce
