USGS: Production Drops in Second Quarter


An estimated 535 million metric tons (Mt) of total construction aggregates was produced and shipped for consumption in the United States in the second quarter of 2011, according to USGS Crushed Stone Commodity Specialist Jason Willett. That represents a decrease of 5.5 percent compared with that of the second quarter of 2010. The estimated production for consumption in the first 6 months of 2011 was 857 Mt, a decrease of 4 percent compared with that of the same period of 2010.

An estimated 311 Mt of crushed stone was produced and shipped for consumption in the United States in the second quarter of 2011, a decrease of 6.5 percent compared with that of the second quarter of 2010. The estimated production for consumption in the first 6 months of 2011 was 507 Mt, a decrease of 4 percent compared with that of the same period of 2010.

“Since Q2 2006, there has been 17 negative quarters in the crushed stone sector, with six of those quarters having double-digit decreases,” Willett said. “Q2 2010, Q4 2010, and Q1 2011 were the only positive quarters since Q2 2006, but the 1 percent increase in Q1 2011 could really be plus or minus 1 percent given that they are estimates.”

The estimated U.S. output of construction sand and gravel produced and shipped for consumption in the second quarter of 2011 was 224 Mt, a decrease of 4.2 percent compared with that of the second quarter of 2010. The estimated production for consumption in the first 6 months of 2011 was 350 Mt, a decrease of 4 percent compared with that of the same period of 2010.

“Since Q2 2006, there has been 18 negative quarters in the sand and gravel sector, with 9 of those quarters have double digit decreases,” Willett said. “Q2 and Q4 last year were the only two positive quarters since Q2 2006.”

The estimated portland cement consumption decreased by 3 percent in the second quarter of 2011 compared with that of the second quarter of 2010. The estimated consumption in the first 6 months of 2011 decreased slightly compared with that of the same period of 2010. This information is obtained from the USGS monthly survey of U.S. cement producers.

The estimates are based on information reported to the U.S. Geological Survey (USGS) on its quarterly sample survey by construction aggregates producers.

The estimated production-for-consumption of construction aggregates in the second quarter of 2011 decreased in seven of the nine geographic divisions compared with that sold or used in the second quarter of 2010. The largest decreases in percentages were recorded in the East South Central and the West South Central divisions. Production-for-consumption decreased in 27 of the 45 states that were estimated.

The five leading states, in descending order of production-for-consumption, were Texas, California, Pennsylvania, Missouri and Ohio. Their combined total production-for-consumption was 157 Mt and represented 29 percent of the U.S. total.

The estimated production-for-consumption of crushed stone in the second quarter of 2011 decreased in six of the nine geographic divisions compared with that sold or used in the second quarter of 2010. The largest decreases were recorded in the East South Central, West South Central, and the East North Central divisions. Production-for-consumption decreased in 28 of the 46 states that were estimated.

The five leading states, in descending order of production-for-consumption, were Texas, Pennsylvania, Missouri, Ohio and Virginia. Their combined total production-for-consumption was 100 Mt and represented 32 percent of the U.S. total.

The estimated production-for-consumption of construction sand and gravel in the second quarter of 2011 decreased in eight of the nine geographic divisions compared with that sold or used in the second quarter of 2010. The largest decreases in percentages were recorded in the West South Central and the Middle Atlantic divisions. Production-for-consumption decreased in 30 of the 47 states that were estimated.

The five leading States, in descending order of production-for-consumption, were California, Texas, Michigan, Wisconsin and Utah. Their combined total production-for-consumption was 73.6 Mt and represented 33 percent of the U.S. total.
