The line graph compares the proportion of Americans in four age groups who used Twitter between November 2010 and May 2013.
Overall, Twitter use rose across all age groups over the period, and the youngest group (18-29) remained the largest and showed the most pronounced growth. Older age bands increased more slowly and stayed considerably lower than the young adult cohort.
In November 2010, roughly 15% of 18-29-year-olds used Twitter; this figure climbed steadily and surged after early 2012 to reach about 30% by May 2013, with a peak slightly above 30% in late 2012. The 30-49 group began at around 8% and rose in a generally steady manner to roughly 15-16% by the end of the period. The 50-64 cohort showed moderate growth from approximately 4% to about 11%, with small fluctuations but a clear upward trend. Usage among those aged 65 and over remained the lowest: it hovered near 2-3% for much of the time before edging up to around 5% by May 2013.
Comparatively, the 18-29 group’s increase was both larger in absolute and relative terms than any other group, while the gap between the youngest and the oldest widened noticeably as Twitter gained popularity
