Included are industries such as primary metals and semi-finished products, as well as goods that are used to make other products, such as engines for cars. Manufacturing's share of intermediate activity is nearly 40 percent. Its share of GDP is 23 percent. When the two are combined, manufacturing's share of total output rises to more than 27 percent. Because total manufacturing output is larger than final sales of manufactured goods, manufacturing's contribution to job and business growth in other sectors is also larger.
Final sales consist of consumer purchases, business investment, government and trade.
This is called a multiplier effect. Manufacturing's multiplier effect is greater than the general multiplier effect of 94 cents for all industries.
