Doing some simple analysis of Facebook users in Australian confirms the belief that we want to be younger (or older); and we’re happy to lie about ourselves to the world.
It also reinforces the uncomfortable feeling I get when researchers (including people in my team) do focus groups, surveys & other prompted research – when you ask someone about their values, views or habits it’s likely that they’re going to lie.
So back to Facebook where we have a very unique scenario, 46% of all Australians 13 yrs+ are on Facebook and they have to answer a series of questions to create an account, resulting in a very large sample size of data, although not many ways to cross tabulate the data.
Using Facebook’s advertising system, where you can build demographic profiles based on all kinds of attributes; you can estimate the number of people in any given segment on Facebook.

Using the tool I discovered the following audience sizes, 25-34 being the largest, and more women than men in every age group.
Australian’s on Facebook (blue) vs. Men (red) vs Women (green)

For kicks I compared these numbers to the actual population in Australia with the intention of understanding the % of Australians in each segment on Facebook. Instead I discovered that Australian’s want to be younger (or maybe older) and are happy to lie about it.
Australian’s (red) vs. Australian’s on Facebook (blue)

The graph above shows the number of Australians in each age group compared with the number of people on Facebook who claim to be the given age.
Digging a little further it was clear the discrepancy was only with the women.
Australian Women (red) vs. Australian Women on Facebook (blue)

And the discrepancy isn’t tiny, it adds up to over 257,000, even with some margins of error that’s a big gap. Another way of looking at it is that there’s 115% of Women aged 25-34 on Facebook, an awesome stat, if only it could be true.

I’m making a big assumption here, as it could be an error, 13 year olds wanting to be 18 or something else, but I believe it’s a reflection on the pressure from society, media & our peers to be and live more youthful lives.
It highlights the impact of the new world we live in where Facebook (and social media generally) plays an interesting role in our social & professional lives, giving us more power to manage our own brand, reputation & image, unless someone else takes control, uploading those awkward photos of us from our best friend’s birthday party.
Oh, and to point out the obvious and the reason I actually did this analysis, 46% of Australians are on Facebook. Just for good measure here’s another pretty chart of visits to three sites in Australia from Google Trends to confirm traffic is trending up or down, and it’s up.
