You got your stats wrong there, Carl. It’s 73% of ONLINE adults – but even in the US, there are 15% of adults who are not online (and in many other countries it is even higher). So that drops the percentage to 62% (in the US). Then you have to do the age calculation – 18-29 year olds have the highest rate of online usage, but while those 65 and older are increasing their online presence, only 43% of Americans over 65 are online. Assuming that 73% of those are using social media, that means less than a third of Americans over 65 are using social media.
Carl, if you want to remain in the majority, stay OFF social media!
