The bar graph illustrates the proportion of the four various age categories using the Internet in Taiwan from 1998 to 2000.
Overall, it is discernible from the graph that the common trend of the percentages from both groups: 16-30 years and 31-50 years increased in three years, while the two remaining groups showed the opposite. Notably, the oldest group above 50 accounted for the least proportion of all four groups.
It can be seen that in 1998, the percentage of people from 16 to 30 years old made up 53%, and it was the highest figure over the period shown. After dropping to 45% a year later, the figure nearly leveled off at this point until 2000. Sharing the same decreasing trend, the middle-aged group (31-50) reached its peak in the first year with 41% before respectively declining by 2% in the following years.
Regarding the remaining groups, despite the lowest fraction in 1998 (2%), the rate of children under 15 using computers jumped 4 times as high as a year ago and kept rising to one more percentage at the end of the period. Meanwhile, the figure for the elderly was witnessed for the growth either. It grew from 2% in 1998 to roughly 8% in 1999, when it equaled the figure for the teenager group in the same year and ended up in 2000 with 10%.
