Work Step by Step
To find the number of Internet users the United Kingdom had in 2010, first we need to locate the United Kingdom bar. Then we match the height of the bar with the value on the vertical axis to approximate the number of Internet users.
The United Kingdom bar is the third bar, if we count from the right side. The height of the bar matches with approximately the frequency of 50 million.
Therefore, there are approximately 50 million Internet users in the United Kingdom in 2010.
