The line graph displays the changes in the number of participants across five activities at a social center in Melbourne, Australia, over two decades, from 2000 to 2020.
The film club attracted the highest number of participants throughout the period, but its figure remained almost stable at 65 despite a drop to 60 in 2010. Martial arts was the second most popular activity during most of the period and saw a similar trend, with participation fluctuating between 30 and 40 over the years.
The trends in the other three activities varied. In 2000, 25 people participated in amateur dramatics. After a slight growth to 28 in 2005, its figure declined gradually to about 5 by the end, making it the least chosen activity. However, the participation in table tennis was steady at 20 in the first decade, followed by a significant rise, overtaking martial arts in 2015 and ending at 55. In comparison, musical performances saw less remarkable growth, starting with zero in 2000, surpassing amateur dramatics, and reaching just under 20 participants by the end of the period.
Overall, with the exception of amateur dramatics, the other four activities grew in popularity. The film club remained the most favored, while amateur dramatics became the least popular.
