The National Association of Manufacturers (NAM) reported that in 2012 the manufacturing industry contributed $1.87 trillion to the U.S. economy, or approximately 11.9 percent of the nation's gross domestic product (GDP). If considered independently, NAM concluded, in 2012 the U.S. manufacturing sector would be the tenth largest economy in the world. Additionally, many jobs in manufacturing pay somewhat higher annual salaries than those in other industries. NAM also reported average earnings of $77,505 for U.S. production workers.
