The given pie charts compare figures for four major purposes of using the phone for (social networks, email, digital camera, and phone calls) by teenagers in a particular African country from 2016 to 2019.
Overall, it is readily apparent that the majority of them used the phone to surf the Internet over the period shown, whereas calling was the least favorite thing to do. Additionally, whilst sending emails and making phone calls witnessed a downward trend, using the Internet and taking photos shown an opposite pattern.
In 2016, the figure for using the Internet was the highest, at roughly 50%, making it the main reason why teens usually used the phone. This is followed by that of sending email, which is only half of that, at around 25%. Using the digital camera and calling were relatively lower, at about 15% and only 10% respectively.
Over the four-year period, the figure for using the social networks rose significantly to reach a peak of around 56%. Similarly, after remaining unchanged for the first 2 years, the proportion of using the camera increased sharply by 5% to reach about 20% in 2019. By contrast, the figure for emailing decreased to 24% in 2017 before a dramatic drop to 19%. Making phone calls continued to be insignificant over the given period, it bottomed out at only 5% by 2019 despite a minimal increase to 13% in 2017.
