The United States exports more cotton than any other country, though it ranks third in total production, behind China and India. Almost all of the cotton fiber growth and production occurs in the Southern United States and the Western United States, dominated by Texas, California, Arizona, Mississippi, Arkansas, and Louisiana. More than 99 percent of the cotton grown in the US is of the Upland variety, with the rest being American Pima. Cotton production is a $21 billion-per-year industry in the United States, employing over 125,000 people in total, as against growth of forty billion pounds a year from 77 million acres of land covering more than eighty countries. The final estimate of U.S. cotton production in 2012 was 17.31 million bales, with the corresponding figures for China and India
