The first bar graph delineates the ownership of smartphones as a percentage of the population between 2000 and 2010, while the second graph depicts the smartphone ownership by the level of educational qualifications in 2000 and 2010.
Overall, according to the first graph, the proportion of smartphone users has increased over the decade constantly. According to the second, individuals with a higher level of education have possessed more smartphones in comparison.
At the outset, 40% of the population possessed a smartphone. This proportion increased to approximately 45% in 2002, and about 50% in 2004. Then there was a sharp growth, with about 60% in 2006, and about 75% in 2008 using smartphones. However, a maximum of about 85% was reached in 2010. Therefore, smartphone ownership gradually grew over the time period.
About 15% and 45% of individuals without a high school certificate possessed a smartphone in 2000 and 2010 respectively, which is three times the increase, in comparison. However, this increased to about 30% in 2000 and 60% in 2010 among high school graduates. 60% and 80% of bachelor’s degree holders had smartphones in 2000 and 2010 respectively.
