Twitter use by age group in the USA

The graph illustrates the usage of Twitter by different age groups in the USA between November 2010 and may 2013. Generally speaking, the trend is upward for all the age groups, with a significant advantage of people aged from 18 to 29. It can be seen that though the proportion of young Twitter users almost remained flat between 2010 and 2011, it actually soared by August 2012, reaching a noticeable peak of 32%. The number of 30-49-year-olds using Twitter rose gradually from 7% to 16% and actually doubled over the period. A similar pattern was seen in the number of people aged from 50 to 64, where the proportion went up steadily from 6% to 12. 5%. The last age group in the chart, Twitter users of 65+, fluctuated slightly during the period from 4% to 6%, showing only 1% increase. In conclusion, the popularity of Twitter is growing especially among the people aged under 65 years old. However, it is used more often by 18-29-year-old Americans.
