The pie charts illustrate the proportion of employees with various qualifications working in an engineering company in the years 1980 and 2008.
In 1980, the most significant portion of employees held a Master’s degree in Science, comprising 29% of the workforce. This was followed closely by those with a Ph.D. in Science, making up 25%. Employees with a Master’s degree in Art constituted 13%, while those with a first degree in Science and Art represented 20% and 11%, respectively. A minimal 2% of the employees held a Ph.D. in Art.
By 2008, there were noticeable changes in the qualifications of the employees. The proportion of those with a Master’s degree in Science remained unchanged at 29%. However, the percentage of employees with a Ph.D. in Science increased significantly to 30%. Those with a Master’s degree in Art saw a slight decrease to 12%, and employees with a first degree in Science remained relatively stable at 12%. The proportion of employees with a first degree in Art decreased slightly to 10%, while those with a Ph.D. in Art experienced a significant increase to 7%.
Overall, the charts reveal a trend towards higher qualifications among the employees over the 28-year period, with a notable increase in the percentage of those holding Ph.D. degrees in both Science and Art. The consistency in the proportion of employees with a Master’s degree in Science highlights its continued importance in the company. However, there is a slight decline in the proportion of employees with lower-level qualifications, indicating a shift towards a more highly educated workforce.
