The provided bar chart compares the proportion of Australian children in three groups participating in four different types of activities by 2018.
Overall, watching TV had the largest share among 5-8 and 9-11 years old children, whereas playing computer games, reading and riding bikes accounted for a small proportion throughout the period. Notably, riding bikes made up the majority of children aged 12-16 while playing computer games consistently represented a modest percentage over the period shown.
As can be seen clearly from the chart, children within 5-8 age group spent nearly 97% of their time to watch TV, making it nearly twice as high as the proportion of playing computer games at around 60%. Likewise, the figures for 9-11 and 12-16 years old group of children were the same in terms of watching television at 80% in the given period.
Meanwhile, children aged group 12-16 showed little interest in playing games on computer, which had roughly 40% compared to a significant share of riding bikes at around 81%. While the ratio of 9-11 years old children joining in watching TV reached 80%, the figure for reading, playing computer games and riding bikes remained relatively stable at 65%, 55% and 60% respectively by 2018.
