The provided pie charts depict the distribution of qualifications among staff in an advertising company for the years 1990 and 2010.
A notable shift in staff qualifications is observed over the two decades, characterized by a significant decline in the percentage of individuals holding first degrees in both science and arts, coupled with an increase in those possessing master’s degrees in science.
In 1990, the qualifications of personnel were primarily composed of master’s degrees in science, accounting for 26% of the workforce, followed by a similar proportion of PhD qualifications in both science and art at 21% and 20%, respectively. By 2010, the scenario changed markedly, with master’s degrees in science rising to 30%. Conversely, the percentage of individuals holding first degrees dropped dramatically, with those in science declining from 12% to 23% and those in art plummeting from 6% to 2%.
The data concerning PhD qualifications reveal a stark contrast; in 1990, individuals with a PhD in science constituted 21%, which fell to 11% by 2010, indicating a significant decline. Meanwhile, the PhD qualifications in art saw a drastic reduction from 20% to a mere 2% in 2010. This trend suggests a sharp decrease in the pursuit of advanced qualifications in the arts field contrasted with modest retention in scientific disciplines, thereby highlighting an evolving professional landscape in the advertising sector over these two decades.
