The bar chart illustrates the comparison of employment across three sectors – agriculture, industry, and services – in three countries: A, B, and C. It also presents the anticipated changes from 1980 to 2020.
Overall, significant changes, including both increases and decreases, are expected in all three sectors. The number of employees in service jobs is projected to grow substantially, while agricultural employment is expected to experience a notable decline. In contrast, industrial jobs will show a more stable distribution.
Firstly, the services sector is anticipated to surge in all three countries. In 1980, all countries except B already saw services as the leading contributor to employment, with about 45% of jobs in A, nearly double that of agriculture, and approximately 70% in C. Although B started with a modest 25% in 1980, it is predicted to rise to over 40%, representing the most significant increase compared to A and C, where service jobs will grow by 5%, moving from 45% to 50% in A and from 70% to 80% in C.
Meanwhile, agricultural jobs are expected to decline consistently across the three regions. In B, where this sector was the largest, accounting for about 55% of employment in 1980, the proportion is expected to decrease by 6%, falling to nearly 50% by 2020. A similar decline is expected in A, where the 20% share of agricultural jobs in 1980 is projected to drop to just 10% in 2020. In C, a minimal decrease of around 1% is expected from its already low percentage in 1980.
In contrast to the other sectors, industrial jobs are projected to exhibit a more mixed pattern. In B, industrial employment is expected to rise significantly from 20% to 40%. However, in C, the sector is anticipated to shrink from nearly 40% to just over 20%. In A, industrial jobs are expected to remain relatively stable, with a slight reduction of approximately 1% from 1980 to 2020.
