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. According to the U.S. Bureau of Labor Statistics, in 2012 overall annual earnings in manufacturing were $51,915 compared to $49,289 annual earnings for all industries.
