If you pay attention to such metrics as have been published over the past year, it probably wonâ€™t surprise you to note that the older you are, the more likely you will be to be a Facebook or Twitter user, according to the study.
This is clearly suggested in the table of generations you see here.
The research relates to users in the USA of the social networks mentioned. Although I donâ€™t know of any similar research for the UK, I wouldnâ€™t be surprised if the picture here isnâ€™t that dissimilar.
Inside Facebook has a good take on the stats:
[â€¦] 75% of Generation Y users (15 to 29 years old) use MySpace compared to Facebook at 65%. Usage of Twitter (14%) and LinkedIn was up for this group. Respondents in the Generation X (30 to 44 years old), baby boomers (44 to 65 years old), and the WWII categories are more likely to use Facebook, followed by MySpace, Twitter, and LinkedIn. In other words, Facebook is becoming a popular site among the older generations â€“ but the more telling stats here would be on growth and engagement.
So Gen Xers are the middle bulge, as it were, on Facebook and Twitter usage in particular. But the heavy users are members of the oldest generation, especially Facebook.
All of distinct interest to marketers, I would imagine.
And if you sometimes scratch your head over labels like Gen X, Y or Z, Inside Facebook helpfully notes the age demographics. This concise description list on Wikipedia will also help.
