Phenomenal Gains in Manufacturing Productivity
The chart above shows annual real manufacturing output per worker from 1947-2010 using data from the BEA for manufacturing output by industry and data from the BLS on manufacturing employment.
In 1950, the average U.S. manufacturing employee produced $19,600 (in 2010 dollars) of output, and by 1976 the amount of output per worker had doubled to $38,500. During that period manufacturing productivity was growing annually at 2.63%. Output per worker doubled again to $75,000 by 1997 (21 years later), as productivity per worker increased to 3.23%. Manufacturing output per worker approximately doubled again to $149,000 by 2010, but it only took 13 years because worker productivity accelerated to 5.42% during this period.
This is an amazing story of huge increases in U.S. worker productivity in the manufacturing sector. In fact, the growth in manufacturing worker productivity more than doubled from 2.63% per year in the period between 1950 and mid-1970s to 5.42% annually between 1997 and 2010. Whereas it took 26 years for output per worker to double during the first period (1950-1976), it only took 13 years during the more recent period (1997-2010).
We are constantly hammered with bad news about the decline in the number of manufacturing jobs in the U.S., but we never hear the good news about why that is happening: Manufacturing workers in America keep getting more and more productive, which then allows us to produce more and more output over time, with fewer and fewer workers. That's a great story about an American industry that is healthy, successful and thriving, and not an industry in decline.
By continually increasing worker productivity and productive efficiency, the American manufacturing sector has been hugely successful at achieving one of the most important economic outcomes of being able to "produce more with less." In the process, those efficiency and productivity gains have helped conserve scarce resources, including human resources, more effectively than almost any other industry, except maybe farming. It's hard to overstate how much the efficiency gains achieved by U.S. manufacturing have contributed to the improvements in our standard of living by making manufactured goods more affordable over time. We should spend less time complaining about fewer workers in manufacturing, and more time celebrating the phenomenal gains in manufacturing worker productivity.
