China became the largest manufacturing economy in the world (with a 23.2 percent share of manufacturing activity) through extremely fast growth in the physical volume of value-added and modest inflation. The U.S. is in second place with a 17.2 percent share. China has more than four times the population of the United States, and though its manufacturing intensity of $1,978 per capita value-added in 2013 is high for a developing economy, it is well behind advanced countries such as the United States ($6,338).
