The given pie charts compare the proportion of people who did voluntary work in different organizations in 2008 and 2014.
Overall, while the percentage of people volunteering for the environment, healthcare services and sports activities followed an upward trend, the reverse pattern was seen in the figure for the remaining groups. Besides, healthcare organizations were staffed with the least volunteers in both years.
In the year 2008, volunteers working in educational organizations accounted for the largest proportion, at 24%, in comparison with 21% and 18% of people volunteering in environmental and art projects respectively. Meanwhile, 15% of volunteers worked in sports organizations, which was the same as the figure for others. Voluntary work related to healthcare, however, was the least common choice among people, with a mere 7% participants.
After 6 years, the percentage of volunteers in educational organizations decreased to 17%. Likewise, the figure for people working in art and other volunteering activities witnessed a fall of 6%. In contrast, there were much more volunteers working in environmental and sports organizations compared to other groups, with 29% and 25% respectively. Activities in the healthcare sector, despite a slight rise of 1% in its figure, remained the least preferred option among volunteers.
