The line chart below shows the percent of American adults who use social networking sites by age between 2005 and 2015. A separate line is used for each age group.
As expected, young adults (18-29) are most likely to use social networking sites. However, adoption for those 65 and older has significantly increased over the last 10 years.
The chart above was built using Aploris. Aploris is a plug-in for PowerPoint (Mac and PC) that enables the effective creation of a variety of insightful charts including waterfall and Mekko charts.
