The diagram compares and predicts the workforce distribution in countries A, B, and C concerning three sectors – agriculture, industry and service – between 1990 and 2030.
Overall, in 1990, service attracted the majority of employees in country A and C, while its workforce represented the second lowest share in country B. Moreover, it is also predicted to be more popular in all three nations, whereas agricultural sector is expected to follow an opposite pattern.
In 1990, the distribution of service employment in country B was just about 25%, slightly higher than the figure for industry at one-fifth and was far exceeded by agriculture at almost 55%. By contrast, service was the most attractive sector in country A and C, whose employees represented around one-half and 60% of the nations’ workforce, respectively. In country A, industry’s employment distribution was 30%, moderately lower than its counterpart in country C at 40%. However, the most significant difference between the two nations was evident in the figure for agriculture. To be specific, while around one-fifth of country A’s workers engaged in agricultural jobs, their counterparts in country C only accounted for around 5%.
Four decades later, service sectors in the surveyed countries are expected to become more popular, with their employment distributions possibly increasing by about 10 to 20%. In details, they will be around 55% in country A, over 40% in country B and almost 80% in country C. Meanwhile, it is predicted that agriculture will witness an inverse trend; its workforce’s proportion will all drop in the three nations, with the most apparent decrease (of around 10%) being in country A. As for industry, while its figure will almost plateau in country A, remaining at around 30%, changes will be apparent in the other nations. Specifically, industry’s distribution will double in country B, in contrast to its 10% decline in nation C.
