The bar charts depict the proportion of smartphone consumers in a country between 2000 and 2010, categorized by different education qualifications.

There was also a significant rise in the rate of phone owners without high school certificatse during this time.

Similarly, High School Graduates who own smartphones witnessed the same pattern, as the number grew dramatically from 30% to 60% in just a decade.
In contrast to noticeable changes of phone ownership with other education levels, the proportion of phone owners who have bachelor’s degrees rose gradually by 20% from 2000 to 2010. Following the similar trend, graduates with master’s degree having phones took the second place in 2010, after moderately increasing from 70% to 85%. Eventually, the proportion of individuals with doctorate degrees owning smartphones maintained the highest position after 10 years at 90%, which doubled the figure for those without a high school certificate in the same year.
