Data Availability

Using the United Nations Statistical Division's Industrial Commodity Statistics for cement, natural sands, and gravel/crushed stone, we developed a measure of the global resource availability. The amount of information available by country varies greatly and is depicted on the map below. The capacity for dredging is derived from the International Association of Dredging Companies' annual report.














Cement

Over the 1995-2006 time frame, cement production tended to cycle once, twice, or not at all (once per 10 years or 5 years, or there was sufficient growth year-over-year to eliminate cyclic industry output). Production trends overwhelmingly indicate strong growth across the industry. The relative production rates are shown below. Our average country data set is 9.85 years in duration. The maximum single-year rate of growth was approximately 10% from 2002 to 2003. We estimate the global cement production capacity to be 2.63 billion metric tons per year.














Natural Sands

Over the 1995-2005 time frame, sand production tended to cycle once or twice (once per 10 years or 5 years, respectively). Production trends indicate low, but steady growth in the industry. The relative production rates are shown below. Our average country data set is 6.51 years in duration. The maximum single-year rate of growth was approximately 11% from 2003 to 2004. We estimate the global sand production capacity to be 1.89 billion metric tons per year.














Gravel and Crushed Stone

Over the 1995-2006 time frame, cement production tended to cycle once, twice, or not at all (once per 10 years or 5 years, or there was sufficient growth year-over-year to eliminate cyclic industry output). Production trends indicate moderate growth in the industry. The relative production rates are shown below. Our average country data set is 6.78 years in duration. The maximum single-year rate of growth was approximately 22% from 2002 to 2003. We estimate the global gravel production capacity to be 3.69 billion metric tons per year.
