The two pie charts illustrate the educational qualifications of staff members in an advertising company in the years 1990 and 2010. The data is categorized into six academic qualifications: First Degree (Art and Science), Master’s Degree (Art and Science), and PhD (Art and Science).
Overall, over the 20-year period, there was a noticeable increase in the proportion of employees with science-related qualifications, particularly at the PhD level. Conversely, the percentage of staff with an art-related first degree dropped significantly.
In 1990, the largest group of staff held a Master’s in Science (29%), followed by those with a Master’s in Art (21%) and a First Degree in Science (20%). A smaller proportion had a First Degree in Art (15%) and a PhD in Science (13%), while only 2% had a PhD in Art.
By 2010, the qualification distribution had shifted. PhD holders in Science rose sharply to 30%, making it the most common qualification. The percentage of staff with a Master’s in Science remained steady at 29%, while those with a Master’s in Art slightly increased to 23%. However, there were significant drops in those with First Degrees in both Art (down to 2%) and Science (down to 11%). Meanwhile, PhD holders in Art increased modestly from 2% to 5%.
In conclusion, the company experienced a clear shift towards employing more highly qualified individuals, especially in scientific disciplines, by 2010.
