The given two pie charts compare 1990 and 2010, illustrating the qualification of staff in an advertising company.

Overall, it is clear that the proportion of staff with a first degree in art and science, albeit the figure for those with a master’s degree in science remained stable over the period. By contrast, the percentage of other qualifications showed an upward trend. Notably, PhD holders in science surpassed those with a master’s degree in science despite accounting for a lower share initially.

In the initial year, those with a master’s degree in science had the highest proportion (29%), nearly one-third of the chart, followed by staff with a master’s degree in art (21%). In contrast, the rate for first degree holders in science (20%) was marginally higher compared to those with a first degree in art (15%). Moreover, the share of PhD holders in science (12%) was six times that of PhD holders in art (2%).

Conversely, the figures for first degree holders in art and science dipped to 2% and 11%, respectively, after two decades. On the other hand, staff with a master’s degree in science levelled off at their initial level. Turning to qualifications that saw a rise, the value for PhD holders in science surged to 30%, leading the chart in the final year. Furthermore, the percentage of PhD holders in art and those with a master’s degree in art marginally grew to 5% and 23%, respectively.
