The bar chart compares people using mobile phones according to age groups in one country from 1998 to 2000.
Overall, people from 31-50, and especially those between 16 – 30 were the primary user demographic in all years despite a noticeable fall in the figures. In contrast, there was an increase in the proportion of phone users in the youngest and the oldest age groups.
There were considerable variations in the phone usage patterns among the two youngest age groups. In 1998, only 2% of those aged less than 15 owned mobile phones while 53% of people from the 16-30 age bracket used such devices. This discrepancy, however, narrowed down over the next years, as the figure for the under-15 group rose to 8%, whereas the 16-30 age bracket saw a decline to 45% in 1999. In the final year, there was a marginal one-percentage-point change in both numbers, with the respective figures of people aged under 15 and those from the 16-30 age bracket standing at 9% and 44%
A similar scenario was observed in the remaining two age groups. Mobile phone users comprised 41% of the 31-50 age category, a figure that then dropped by 2-percentage points in each subsequent year, finishing at 37% in 2000. Meanwhile, the figure trended upward for the oldest age group. Starting at just 4% in 1998, it then doubled in 1999 before increasing further to 10% in 2000.
