The bar graph delineates the distribution of three disparate job fields, namely agriculture, services, and industries, in three nations from 1980 and prediction until 2020.
Overall, while agriculture in three countries is expected to decline, the reverse pattern is anticipated considering services. Additionally, whilst the majority of employment in country A and C belonged to services and is projected to still be on top, country B displayed a strong reliance on agriculture and is predicted to stay the same throughout.
Regarding country A, jobs related to services ranked first, at nearly 45% and are forecasted to surge to roughly 55% in 2020, maintaining a strong margin with other sectors. Conversely, both agriculture and industry are expected to drop from 20% and 30% to 10% and around 28%,respectively.
Turning to country B, the distribution proportions of industry and services in 1980 were approximately 20%, whereas agriculture accounted for 55% of employment. However, the figure for agriculture is predicted to be nearly 50%; meanwhile, the other two categories are anticipated to be around 40% in 2020.
Concerning country C, agriculture had the least popularity in 1980, and the projected statistics also show that its percentage will drop to nearly 2%. Likewise, the proportion of industry is forecasted to decrease to roughly 25% in 2020. In contrast, the graph indicates that services will escalate from 70% to nearly 80% eventually.
