The figure illustrates how many gigabytes used each month by four age groups in 2020.
Overall, the figures for 18-25 year olds and 26-35 year olds underwent noticeable variations, whilst the figures for people above 32 varied moderately. Additionally, 26-35 year olds used more gigabytes in the beginning, but by the end the figures for 18-25 year olds dominated.
Turning to details, 18-25 year olds’ initial usage stood at roughly 120 gigabytes, while that of 26-35 year olds started at 150 gigabytes. In the following 2 months, the gap between figures for 18-25 year olds and 26-35 year olds shrunk over time until they converged at nearly 150 gigabytes. Over the course of 10 months, the figure for 26-35 year olds displayed significant instabilities, before reaching almost 165 gigabytes. In the same way, the figure for 18-25 year olds also varied greatly, reaching its peak value of 200 gigabytes by surpassing those for 26-35 year olds.
Considering the other age groups, the figures for 36-50 year olds and that of above 51 year old exhibited same patterns of change until April with rates of 100 gigabytes and 80 gigabytes, respectively. After experiencing some limited fluctuations, the figure for 36-50 year olds presented a gradual increase to just below 165 gigabytes. By comparison, the figure for those above 51 year old showed slight fluctuations between May and December, from 110 gigabytes to 120 gigabytes, reaching its highest point.
