The bar chart compares mobile phone usage among different age groups within a single country from 1998 to 2000.
Overall, it is evident that individuals aged 31-50, and particularly those aged 16-30, constituted the primary user demographic in all years, despite a noticeable decline in the figures. In contrast, there was an increase in the proportion of phone users in the age groups under 15 and over 50.
Considerable variations in phone usage are observed between the two youngest age groups. In 1998, only 2% of those aged under 15 owned mobile phones, while conversely, 53% of individuals in the 16-30 age cohort used such devices. However, this gap narrowed over the following years, with the figure for the under-15 group rising to 8%, whereas the 16-30 age group witnessed a decrease to 45% in 1999. By 2000, there was a slight change in both figures to approximately 1%, with the respective proportions of individuals aged under 15 and those in the 16-30 age group standing at around 9% and 44%, respectively.
