The U.S. Geological Survey reports that an estimated 255 million metric tons of crushed stone was produced and shipped for consumption in the United States in the fourth quarter of 2009, a decrease of 20% compared with that of the same period of 2008. The estimated annual output of crushed stone produced for consumption in 2009 was 1.11 billion metric tons, a 23% decrease compared with that of 2008.
The estimated output of construction sand and gravel produced and shipped for consumption in the fourth quarter of 2009 was 177 million metric tons, a decrease of 22% compared with that of the same period of 2008. The estimated annual output for 2009 was 776 million metric tons, a 25% decrease compared with 2008.
An estimated 432 million metric of total aggregate was produced and shipped in the fourth quarter of 2009, a decrease of 21% compared with that of the same period of 2008. The estimated annual output of aggregate produced for consumption in 2008 was 1.88 billion metric tons, a 24% decrease compared with that of 2008.
These estimates are based on information reported to the U.S. Geological Survey quarterly sample survey by crushed stone and construction sand and gravel producers.
The estimated portland cement consumption decreased by 25% in the quarter and decreased by 27% in annual consumption for 2009, compared with consumption in 2008. This information is obtained from the USGS monthly survey of U.S. cement producers.
Production-for-consumption estimates are generated independently for each state, each geographic division, and the 48 conterminous states, which are treated as separate statistical sample areas. Therefore, differences may exist between the total for a division and the sum of the State totals in the same geographic division. Similarly, differences may exist between the estimates of total aggregates and the estimates of crushed stone and construction sand and gravel for a specific statistical area.
This is a sample survey that generates production-for-consumption estimates by quarters, based on information reported voluntarily by a limited number of producing companies. Occasionally, some companies revise previously reported data; the estimated quantities for the prior quarters are then recalculated. The latest release of the quarterly Mineral Industry Surveys contains the most recent estimated totals and percentage changes and supersedes previously published reports.
The estimated production-for-consumption of crushed stone in the fourth quarter of 2009 decreased in all of the nine geographic divisions compared with that sold or used in the fourth quarter of 2008. The largest decreases were recorded in the Mountain (28%) and the West South Central (27%) divisions. Production-for-consumption of crushed stone decreased in 42 of the 47 states that were estimated. The five leading states, in descending order of production-for-consumption, were Texas, Pennsylvania, Missouri, Illinois, and Kentucky. Their combined total was 80.2 million metric tons and represented 31% of the U.S. total.
The estimated production-for-consumption of construction sand and gravel in the fourth quarter decreased in all of the nine geographic divisions. The largest decreases were recorded in the West South Central (32%) and the East South Central (32%) divisions. Production-for-consumption of construction sand and gravel decreased in 41 of the 46 states that were estimated. The five leading states, in descending order of production-for-consumption, were California, Texas, Arizona, Colorado, and Michigan. Their combined total production-for-consumption was 55.6 million metric tons and represented 31% of the U.S. total.
The estimated production-for-consumption of aggregate in the fourth quarter decreased in all of the geographic divisions. The largest decreases were recorded in the West South Central (29%) and the Mountain (24%) divisions. Production-for-consumption of aggregates decreased in 44 of the 48 states that were estimated. The five leading states, in descending order of production-for-consumption, were Texas, California, Pennsylvania, Illinois, and Ohio. Their combined total production-for-consumption was 121 million metric tons and represented 28% of the U.S. total.
