The graph illustrates the quantity of workers in the automotive workforce in four different United States, namely Michigan, Ohio, Indiana, and Alabama over a 20-year period, between 1990 and 2010.
Overall, it is clear that employment in the automotive sector declined in two of four states, namely Michigan, and Ohio. In contrast, Alabama was only state to experience a rise in its workforce over a 15-year period.
In 1990, Michigan had the largest workforce in the motor-vehicle industry with approximately 105,000 workers. This trend fluctuated for the next a decade before undergoing a steady decline, dropping sharply to around 40,000 in 2010. Similarly, Ohio, the number of workers started with about 40,000 employees, also experienced a significant fall, ending at 19,000 in 2010.
In contrast, Alabama was the only state to demonstrate a positive trend line, which started at the lowest point of four states with just under 5,000 workers in 1990, and then its employment numbers saw a gradual climb to finish around 15,000 in 2010.
