The line graph compares the proportions of teenagers using various communication methods among each other in a particular state in the US, from November 2006 to September 2009.
Overall, communication preferences for text messages and phone calls showed an upward trend, while the usage of email declined. Face-to-face interactions experienced fluctuations over the three-year period.
In November 2006, just under 30% of teenagers communicated through text messaging. This figure rose by about 10% by November 2007, remaining below 40%. However, by the end of the observed period, the proportion surged to approximately 55%. In contrast, around 15% of teenagers used email at the beginning, and although this figure continued to rise through the following year, it dramatically declined, ultimately becoming the least popular communication method.
Throughout the period, phone calls and face-to-face conversations remained relatively close in popularity. However, phone calls consistently increased, while face-to-face communication fluctuated by around 10%. By September 2009, both methods of communication had reached approximately 40%.
