Gender effects social media use.
Another great chart from Marketing Charts. This one chronicles social media adoption in the general population and by gender. There is a lot of interesting information that comes out of this graph and some of it matches stereotypes. Pintrest is vastly more popular among females. This is not very surprising but if you are primarily marketing to women this means that you should really be using Pintrest!
I find it very interesting that there are only three social networks that comes in stronger for males than females: Google+, Linkedin and Vine. The running joke for a while was that only Google employees were on Google Plus and well Google has a propensity to hire males (83% are males). This could be the explanation or it might have to do more with cultural tendencies for employment. This article indicates that almost 2/3 of business owners and those who are self employed are males.
Google requires Google Plus pages for the business map pages. Linkedin is the business social network. This is probably not the only factor but it might help explain the disparity. I think these adoption statistics will change in the coming years as women become more empowered in our society.
It is also interesting that a 6% larger share of males ignore social media all together.
