The forecast for industrial sand and gravel sold or used in California from 2024 to 2028 shows a consistent downward trend, decreasing from 791.2 thousand metric tons in 2024 to 713.0 thousand metric tons by 2028. Comparing the forecasted volumes with the previous year's actual figures, if data from 2023 were available, it would allow for a more nuanced understanding of the percentage change in volume. The compounded annual growth rate (CAGR) over this five-year period projects an overall decline, reflecting adjustments in demand or changes in production capabilities.

Future trends to watch for include:

Potential regulatory changes affecting the mining industry in California.
Technological advancements in production and sand and gravel substitutes.
Variations in demand driven by construction activities and infrastructure developments.
Sustainability and environmental policies impacting extraction processes.
