D omestic production data for crushed stone were derived by the U.S. Geologi- cal Survey (USGS) from voluntary sur- veys of U.S. producers. In 2013, a total of 1,457 companies produced or sold crushed stone from 3,688 operations with 3,837 quarries and 204 sales and/or distribution sites. A total of 1.30 bil- lion short tons of crushed stone was produced for consumption from surface and underground mines, a slight increase from the total production of 2012, but 34 percent less than the record high of 1.96 billion short tons in 2006. The value of the crushed stone produced was $11.8 billion, an increase of 3 percent compared with that of 2012. The aver- age unit value for crushed stone increased slightly compared with the average unit value for 2012. After the relatively constant levels of the past five years, including the small increases of 2012 and 2013, production still remains lower than the level of crushed stone production for consumption in the United States in 1994. The total number of em- ployees working at construction aggregate mines has decreased every year since 2006. Employment is down 20 percent compared with 2006 at mines identified as producing crushed stone by the Mine Safety and Health Administration. The 10 leading crushed stone producing states were, in descending order of tonnage, Texas, Penn- sylvania, Missouri, Florida, Ohio, North Carolina, Ken- tucky, Illinois, Virginia, and Indiana. The combined production of the 10 leading states increased slight- ly from 2012 to 671 million short tons, accounting for more than one-half of the national total. In 2013, underground production, totaling 76.8 million short tons, accounted for 6 percent of the U.S. production of crushed stone. Crushed stone was produced in 87 underground mines in 17 states. The five leading states were, in descend- ing order of underground production, Kentucky, Missouri, Pennsylvania, Illinois, and Iowa. Pro- duction from these five states represented 68 percent of the U.S. crushed stone produced from underground mines. The 25 leading companies, in descending order of crushed stone production in 2013, are listed on page 16. These companies, with 1,124 active operations that produced rock from 996 quarries, accounted for 56 percent of the production of crushed stone in the United States. Using the Pa- reto principle, also known as the 80–20 rule, the combined production of the leading 291 compa- nies was 1.14 billion short tons. This means that 20 percent of the companies produced 88 percent of the total sales of crushed stone in 2013. A total of 321 crushed stone operations were either idle or presumed to have been idle in Crushed stone production figures show an increase in domestic production.
