The line chart compares workforce distribution across three different sectors in the United States from 1975 to 1982, together with projections up to 2025. Overall, the most striking trend is the stark contrast between agriculture and services, with the agricultural sector experiencing a significant decline in its workforce, while the service sector shows a marked and sustained increase. Interestingly, the manufacturing sector initially mirrored the service sector’s growth during the first five years but later followed a decline similar to that of agriculture.
It is noteworthy that all figures converged at 40% in 1980. The proportion of services doubled from 20% to 40% in 1980, a trend almost exactly mirrored by manufacturing, which rose from just under 20% to the same level. Meanwhile, agriculture, although it commenced with by far the highest figure at 80% and remained unchanged for the first two years, experienced a substantial decline to 40% over the next three years.
From 1980 onwards, the picture was very different. Services continued its upward trend and is projected to reach 90% in 2030, widening the gap between itself and the remaining categories. In contrast, manufacturing and agriculture are expected to continue their decline, with both sectors projected to have about 10 million workers by 2025.
