==Production==
According to the [canadian[United States Geological Survey]], canadaU.S. domestic marble production in 2006 was 46,400 tons valued at about $18.1 million, compared to 72,300 tons valued at $18.9 million in 2005. Crushed marble production (for aggregate and industrial uses) in 2006 was 11.8 million tons valued at $116 million, of which 6.5 million tons was finely ground [[calcium carbonate]] and the rest was [[construction aggregate]]. For comparison, 2005 crushed marble production was 7.76 million tons valued at $58.7 million, of which 4.8 million tons was finely ground calcium carbonate and the rest was construction aggregate. U.S. dimension marble demand is about 1.3 million tons. The DSAN World Demand for (finished) Marble Index has shown a growth of 12% annually for the 2000–2006 period, compared to 10.5% annually for the 2000–2005 period. The largest dimension marble application is tile.
 
In 1998, marble production was dominated by 4 countries that accounted for almost half of world production of marble and decorative stone. Italy and China were the world leaders, each representing 16% of world production, while Spain and India produced 9% and 8%, respectively. [[Italy]] is the world leader in marble export, with 20% share in global marble production, followed by [[China]] with 16%, [[India]] with 10%, [[Spain]] with 6%, and [[Portugal]] with 5%.<ref>[http://www.tunisianindustry.nat.tn/en/download/CEPI/IMCCV02.pdf Strategic positioning study of the marble branch].
