The provided line graph displays the use of Twitter among several age groups in the USA during the time period from November 2010 to May 2013.
In general, it can be clearly seen that while Twitter usage rose for everyone, with noticeable fluctuation, people aged 18-29 used it significantly more compared to the others.
For example, use of Twitter in the group 18-29 jumped more than twofold, between about 14% and 30% over the period, with peak of around 32% in August 2012. By contrast, usage of Twitter among those above the age of 65 witnessed the lowest contribution, the use was slightly upward with some noticeable fluctuations and it peaked at about 6% in May 2011, while it was roughly 4% at the beginning and 5% at the end of the timeframe. As the diagram depicts, the rise in Twitter use among middle-aged people whose ages range from 30 to 49 was dramatic, increasing by over 150%, from approximately 7% in November 2010 to around 17% in May 2013. A similar surge was seen in the 50-64 age group, whose climbed from about 6% at the start of the period to about 13% by May 2013.
