Overall, employment in manufacturing and agriculture spheres slightly declined but rapidly increased in retail and healthcare throughout the period.
Manufacturing and agriculture sectors decreased with fluctuations and consistency, respectively. At the start, there were 15 million people in the manufacturing sphere, whereas this number was around 3 times less for farmers. In 1980, the manufacturing sphere rose by 5 million vacancies, whereas the agriculture sector experienced its biggest fall and lost half of employees. In 2000, the manufacturing sector had a dramatic change and had around 17 million employees; in contrast, farming did not see any change. On the last part of the data, manufacturing and agriculture spheres declined and ended up with approximately 13 and 2,5 million workers, respectively.
At the start of the illustration, both retail and healthcare systems had the least amount of workers, slightly over 5 million and 2.5 million, respectively. In 40 years, they both increased dramatically and they amounted to 15 and just above 10 million employees in retail and healthcare services, respectively. In 2020, they finally end up meeting each other on the number just above 15 million and placed on the top of the list by the amount of employees. Additionally, the number of workers in all spheres were nearly 15 million with the exception for agriculture which was around 2.5 million.
