The bar chart elucidates the comparison between three fields of employment – agriculture, industry, and services – in three countries – A, B, and C – as well as the estimated shift of them from 1980 to 2020.
Overall, significant and noticeable changes, which consist of both increases and decreases, are expected to occur in all three of the listed fields. The number of employees working in service jobs led the three with its noticeable growth, while agricultural jobs experienced the most remarkable drop, and industrial jobs maintained their distribution.
Firstly, the services industry was speculated to surge among all three countries. In 1980, except for B, this field was already the most prominent contributor, accounting for around 45% of employment in A, nearly twice as much as agriculture, and approximately 70% in C. Despite the insignificant initial state of 25% proportion in 1980, the rising rate of service jobs in B to more than 40% is the biggest surge, compared to the 10% increase in both A and C, which went from 45% to 50% and 70% to 80%, respectively.
Meanwhile, agricultural jobs across the three regions shared the same drop in the number of employees. In B, where it was the biggest contributor, taking up to around 55% of employment in 1980, this field was surmised to decrease by 6%, reaching up to nearly 50% in 2020. A resemblance to this reduction would take place in A, with the 20% proportion in 1980 declining to half of it in 2020, and, similarly, in C, with the unremarkable loss of around 1% from its already small significance in 1980. Despite all this, industrial jobs projected a more variable pattern of both surging, from 20% to 40% in B, shrinking, from nearly 40% to merely more than 20% in C, and steadiness, with an inconspicuous 1% reduction between 1980 and 2020, in A.
