The line chart illustrates the distribution of the workforce in the USA since 1975 and offers its projections until 2025.
Overall, while the services discipline has undergone a remarkable increase in popularity and may maintain this upward pattern later on, the inverse trend is true for agriculture. In addition, the manufacturing sector is likely to experience no change in its contribution and consistently remain at the lowest end throughout the period.
In 1975, agriculture dominated the USA workforce with 80%. This number was maintained until 1977, before plummeting significantly to just 10% by 2025, equal to an eightfold decrease.
Turning to services and manufacturing, both commenced with 10% in 1975 and virtually shared the same pattern until 1980. At this point, three sectors similarly converged at 40%, but then services skyrocketed and are expected further surge to 90% by 2025, whereas manufacturing may again revert to its initial level (10%).
