The chart gives information about the percentage of employees with various university degrees in a particular engineering company from 1980 to 2008.
At the beginning of the period, the largest proportion of workers in the organization had a master’s degree in science, accounting for 29%, followed by those with a Ph.D in science, making up 25% of the total. First degree in science was the third most common qualification among the employees, at one-fifth. The figures for master’s and first degrees in art were fairly similar, constituting 12% and 10% respectively, while workers possessing a Ph.D in art commanded the smallest share, at merely 2%.
In 2008, however, graduates with a Ph.D in science took the lead, reaching 30% on a percentage basis, while those with a master’s degree in science plateaued in terms of proportion, albeit now claiming the second spot in the chart. The figures for first degree in science and master’s in art overlapped at 12% each, with that of first degree in art trailing behind with 10%. Despite a noticeable increase in percentage, Ph.D in art still remained the least common university degree amidst the workers, at 7%.
In summary, over the timeframe given, the proportions of graduates with a Ph.D in science and art witnessed an upward trajectory, while the reverse was true for the percentage of workers owning a first degree in art and science and master’s degree in art. Of particular note is the figure for master’s degree in science, which remained unchanged between 1980 and 2008.
