The charts compare the proportions of the workforce employed in agriculture, industry, and services in three countries in 1990 and the projected figures for 2020.
Overall, employment patterns shift away from agriculture towards services in all three countries. By 2020, services are expected to be the dominant sector everywhere, while agriculture either declines significantly or remains minimal.
In Country A, services already accounted for the largest share in 1990, at about 45%, followed by industry at 30% and agriculture at 20%. By 2020, the service sector is projected to rise further to approximately 55%, while industry increases modestly to around 30%. In contrast, agricultural employment is expected to fall sharply to about 10%.
A different trend is observed in Country B. In 1990, agriculture was the dominant sector, employing roughly 55% of the workforce, whereas industry and services accounted for around 20% and 25% respectively. By 2020, agricultural employment is predicted to decline to about 45%, while both industry and services rise, reaching approximately 40% and 45%.
Country C shows the most service-oriented structure. In 1990, services employed around 40% of workers, compared with roughly 20% in industry and only about 5% in agriculture. By 2020, services are projected to expand further to 50%, while industry decreases slightly and agriculture remains negligible.
