The bar graph illustrates how the proportion of internet shoppers in Australia by six different age groups changed over a two-year period, commencing in 2007.
Overall, it is clear from the graph that shopping was more popular in 2009 than in 2007, with 36-45 aged people recording the highest figure, while the reverse was true for people who aged over 65. It is also worth mentioning that all age cohorts witnessed stable increase throughout the timeframe.
In 2007, people who aged 15-25 and 26-35 recorded a similar patter, albeit to different rates. The former started at 20% and then increased slightly in 2009 to approximately 23%, whereas, at a start, the shares of the latter accounted for just above 30% and then represented a negligible increase in 2009 to about 33%.
By contrast, the figure for 45-55 and 56-65 age cohorts recorded a moderate growth, the first category increased by 5% to 2009, the second one grew from just over 12% to roughly 18% at the end of the period.
As for remaining figures, 36-45 aged people and 65 over people represented a significant growth. People who aged 36-45 stood at 25% initially and then the proportion of this category who shopped online increased dramatically in 2009, hitting a peak of just under 40%. While the percentage of 65+ people experienced the least position among the other age cohorts, with starting at 5% at the beginning of the year, the figure then increased significantly by 2009 to 13%.
