A recent report from Georgetown University’s Center on Education and the Workforce (CEW) details the changes in manufacturing’s geographic concentration across the country between 1940 and 2016. Manufacturing was the largest source of employment in 15 states in 1940, concentrated in the Northeast and Midwest, and had grown to the largest source of employment in 18 states by 2000, concentrated in the Southeast and central states. However, manufacturing was the largest source of employment in only Indiana and Wisconsin by 2016.
