The graph illustrates changes in the number of jobs across four major sectors of the US economy between 1960 and 2020.
Overall, the period witnessed a clear structural shift in employment. While jobs in services rose dramatically to become the dominant sector, agriculture experienced a steady and substantial decline. Manufacturing showed a more moderate trend, peaking mid-period before falling, whereas the fourth sector remained relatively smaller but demonstrated gradual growth.
In 1960, agriculture accounted for a significant share of employment; however, its workforce consistently decreased over the following six decades, reaching its lowest level by 2020. In contrast, the service sector expanded sharply throughout the entire period, overtaking all other sectors by a wide margin and becoming the primary source of employment in the US economy.
Manufacturing jobs increased slightly during the early decades, reaching a high point around the late 20th century, before declining noticeably towards the end of the period. Meanwhile, employment in the remaining sector grew steadily, although it never approached the levels seen in services.
In conclusion, the data clearly reflect the long-term transition of the US economy away from traditional industries towards a service-oriented employment structure.
