The bar chart illustrates the proportion of mobile phone users in a particular country categorized by age group across three years: 1998, 1999, and 2000.
Overall, the data reveals that the proportion of individuals using mobile phones increased in the country over the three-year period. Notably, mobile phone usage amongst younger age groups, particularly those aged 16-30, was significantly higher than in older groups throughout the period.
In 1998, the majority of mobile phone users belonged to the 16-30 age group, with a considerable 53% usage rate. The 31-50 age group followed with 41% usage, while individuals below 15 years old and those aged 50 or more accounted for a considerably lower percentage, with only 2% and 4% respectively. By 1999, the usage rates for all age groups showed an increase, with the most notable change in the ‘less than 15’ group where usage rose to 8%, more than quadrupling compared to the previous year.
While the percentage of mobile phone users in the 16-30 group slightly decreased from 53% to 45% in 1999, it remained the largest age group using mobile phones. The 31-50 age group also saw a modest decrease to 39%. In 2000, mobile phone usage among the 16-30 group decreased further to 44%, yet remained the highest across age groups. The ‘less than 15′ group increased their utilization to 9%, while the ’50 or more’ age group reached 10%. Notably, the usage rate for those aged 31-50 continued to decline, reaching 37% in 2000.
