The given charts delineate the proportion of students joining different courses, according to statistics recorded in 1985 and this year at an adult education center.
Overall, while music appreciation and local history were only available in the year 1985, IT has been introduced this year as a substitution for the two mentioned courses. In addition, while the enrollment rate of fitness and dance remained consistent, those for the other courses underwent certain changes across the two surveyed years.
An in-depth analysis of the charts reveals that art and modern languages both experienced a downturn in popularity among students at the center. The proportion of participation in art slightly diminished from 17% to 15%. Similarly, there was a decline by 7% in the figures for languages classes overtime, which currently reaches the same rate as art recorded in 1985. In contrast to stable enrollment rate seen in fitnesss and dance, fewer students sign up for cookery, as the percentage dropped from 22% in 1985 to 22% this year.
With regard to other courses, local history and music appreciation were provided exclusively in the first year, respectively accounting for 15% and 8% in total. This year, in replacement for the two courses, the center has opened IT classes which attract an enrollment proportion of 27%, the largest portion among all courses.
