The pie charts illustrate the qualifications of staff within an advertising company in 1990 and 2010.
Overall, while the proportion of employees with a First Degree decreased noticeably over time, the reverse was true for PhD holders. The percentage of workers with a Master’s Degree remained relatively stable during the period, showing a little change. The share of PhD-Science Degree holders showed the most significant change in 2010.
Starting at 35% (Science-20%, Art-15%) in 1990, the proportion of staff with a First Degree dropped significantly to 13% (Science-11%, Art-2%) by 2010. The share of workers with a PhD started at 15% (Science-13%, Art-2%) in 1990, a figure that then grew steadily, reaching 35% (Science-30%, Art-5%) by 2010.
However, the percentage of Master’s Degree holders remained relatively unchanged throughout the period, rising marginally from 50% (Science-29%, Art-21%) in 1990 to 52% (Science-29%, Art-23%) in 2010. It was clear that the staff with a Master’s Degree were more appreciated than other workers.
