Usgs: Aggregate Up In Q2


The U.S. Geological Survey reports that an estimated 331 million metric tons of crushed stone were produced and shipped for consumption in the United States in the second quarter, an increase of 6.4% compared with the second quarter of 2009

The U.S. Geological Survey reports that an estimated 331 million metric tons of crushed stone were produced and shipped for consumption in the United States in the second quarter, an increase of 6.4% compared with the second quarter of 2009. The estimated production for consumption in the first six months was 525 million metric tons, a slight decrease compared with that period in 2009.

The estimated output of construction sand and gravel produced and shipped for consumption in the second quarter was 217 million metric tons, a slight increase compared with the second quarter of 2009. The estimated production for consumption in the first six months was 339 million metric tons, a 3% decrease compared with that period in 2009.
An estimated 548 million metric tons of total construction aggregates were produced and shipped for consumption during the second quarter, an increase of 4.8% compared with the second quarter of 2009. The estimated production for the first six months was 864 million metric tons, a slight decrease compared with that period of 2009.

The estimated Portland cement consumption increased by 3% in Q2 compared with that of 2009. The estimated consumption in the first six months decreased 5% compared with that period of 2009.

These estimates are based on information reported to the USGS on its quarterly sample survey by construction aggregates and cement producers. This sample survey generates production-for-consumption estimates by quarters, based on information reported voluntarily by a limited number of producing companies. In most quarters, a few companies may report amounts sold in the current quarter that vary greatly from the amounts reported in the previous year during the same quarter. This change in sales is almost never an indicator of the change in the demand in the state as a whole. The usual cause behind a large change can be attributed to the opening or closing of an operation, weather or an external force that only the company or one of its operations experienced in that quarter. Previously reported data are occasionally revised, and 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 supersedes previously published reports.

The estimated production for consumption of crushed stone in the second quarter increased in eight of the nine geographic divisions compared with that sold or used in the second quarter of 2009. The only decrease was recorded in the Pacific division. The largest increases were recorded in the West South Central, East South Central, and the West North Central.

Production for consumption decreased in only 13 of the 47 states that were estimated. The five leading states, in descending order, were Texas, Pennsylvania, Missouri, Illinois and Virginia. Their combined total was 108 million metric tons and represented 33% of the U.S. total.

The estimated production-for-consumption of construction sand and gravel in the second quarter increased in five of the nine geographic divisions compared with that sold or used in the second quarter of 2009. The largest decreases in percentages were recorded in the New England and the Mountain divisions. The largest increases in percentages were recorded in the Middle Atlantic and the West South Central divisions. Production for consumption decreased in 23 of the 46 states that were estimated. The five leading states, in descending order, were California, Texas, Arizona, Michigan and Minnesota. Their combined total production for consumption was 67.4 million metric tons and represented 31% of the U.S. total.

The estimated production for consumption of construction aggregates in the second quarter increased in six of the nine geographic divisions compared with that sold or used in the second quarter of 2009. The largest decreases in percentages were recorded in the Mountain and the Pacific divisions. The largest increases in percentages were recorded in the West South Central, East South Central and the West North Central divisions. Production for consumption decreased in 22 of the 48 states that were estimated. The five leading states, in descending order of production-for-consumption, were Texas, Pennsylvania, California, Missouri and Indiana. Their combined total production for consumption was 158 million metric tons, which represented 29% of the U.S. total.
