The given bar chart compares the percentage of people by age of those who used the Internet in Taiwan. The data were recorded in 1998, 1999, and 2000; the age cohorts are people who were younger than 15, from 16 to 30, up to 50, and more than 50 years old.
Overall, one of the most striking features when looking at the chart is that over the given period, the proportions of people from two middle age groups who used the Internet decreased, while those of the youngest and oldest brackets witnessed an upward trend. Notably, despite the aforementioned decline, the figures for those from 16 to 50 years old using the Internet in this nation were still much higher than the other two.
Looking first at the 16-30 and 31-50 brackets, which had the highest shares of people who used the Internet. Initially, there were approximately 55% and 40% of people, respectively, who did so. Nevertheless, these numbers decreased significantly a year after to two different extents. Specifically, while the former dropped to only around 45%, that of the latter slightly declined to under two-fifths of the total number of people whose ages were in the range. Until the end of the period, both age groups experienced a plateau regarding their internet usage proportion.
Moving on to the remaining groups, in 1998, only 2% of the people who were under the age of 15 used the Internet, while that of those in the oldest cohort was slightly higher at approximately 4%. These figures were around 10 to 20 times lower than that of the middle groups. However, they experienced a reverse trend, as the shares rose dramatically to reach around a tenth 2 years later.
