The given bar chart illustrates the proportions of Internet users divided into four different age groups in Taiwan over a three-year period, starting from 1998.
Overall, it can be seen that the percentage of people using the Internet from 16 to 30 years of age was in the majority. Besides, the proportion of Internet users who are under 15 and the elderly group over 50 increased, while that from 16 to 50 years witnessed a fall.
In 1998, people aged 16–30 years accounted for over half the Internet usage, followed by users from 31–50 years with 40%. A decline was experienced in those two age groups in the following year; the figure for the 31–50-year-old group fell to 38%, while that in the 16–30 age group decreased significantly by around 10%. At the end of the given period, Internet usage in Taiwan among users from 16–30 remained stable. Regarding the figure for those aged 31–50 years, the year 2000 saw a moderate drop, claiming approximately one-third.
In terms of usage, children and the elderly group comprised a tiny fraction, at around 2% and 5%, respectively. However, in the remaining years of the given period, considerable growth was witnessed, with a triple increase in the figure for the under-15 age group and a double increase for the over-50 age group. In 2000, a slightly increased trend was still seen in Internet usage in those groups, with those groups making up nearly one in ten.
