The two pie charts compare the proportions of graduates with different qualifications in science and art who worked for a particular engineering company in 1980 and 2008.
**Overall,** the proportion of employees with Ph.D. qualifications increased in both fields, while the shares of first-degree graduates declined. The percentage of science graduates with a Master’s degree remained unchanged.
In 1980, **Master’s graduates in science** formed the largest group, at **29%**, followed by **Ph.D. graduates in science**, at 25%. First-degree science graduates accounted for 20%, while Master’s and first-degree art graduates represented 13% and 11%, respectively. Ph.D. graduates in art made up only 2%.
By 2008, **Ph.D. science graduates** had become the largest group, rising to **30%**. The proportion of Ph.D. graduates in art also increased significantly, from 2% to 7%. In contrast, first-degree science graduates fell from 20% to 12%, while first-degree art graduates decreased slightly from 11% to 10%. The share of Master’s science graduates remained at 29%, whereas Master’s art graduates declined marginally to 12%.
