The bar charts illustrate the distribution of employment across three sectors – agriculture, industry, and services – in three different countries, showing actual figures for 1980 and projections for 2020.
Overall, over the 40-year period, the percentage of employment in the services sector in all three countries was predicted to rise to varying degrees. In 1980, industry was the dominant sector in Country A and Country B, while agriculture was more prominent in Country C. Specifically, in 1980, the industrial sector accounted for the largest share of employment in Country A and Country B, at 55% and 65% respectively. In contrast, agriculture was the leading sector in Country C, comprising 60% of the workforce.
By 2020, it was projected that services would become the main occupation in all three countries. Country B was expected to take the highest position, with 65%, while Country A was not far behind, at 60%. Country C was predicted to experience a dramatic surge from 5% to 45%.
In conclusion, the shifts in employment patterns were most evident in the first two countries, with a clear transition from industry to services.
