I’ve been playing around with our Facebook demographics tool for the past few weeks and trying to come up with some interesting statistics. One interesting chart that I’ve come up with is countries sorted by Facebook market saturation. The statistics turned up some interesting numbers. Iceland for instance has the highest market saturation with over 41 percent of the population having a Facebook presence.

Surprisingly enough, the United States came in 17th despite it being the country which Facebook launched in. Not surprising was Canada and the United Kingdom’s presence in the top 6 countries ranked by market saturation. It would also be interesting to order market saturation as a percentage of those individuals with internet access. Unfortunately the most recent statistics that I could find were from 2000 which would be highly inaccurate by now.

As Facebook grows in size, it’s key for the site to focus on expansion within those countries that have lower market saturations. Top countries tend to increase virally whereas many of the countries with lower saturations require additional investment in marketing. In Germany Facebook has tried a number of methods for increasing their presence, and the same goes for countries like the Netherlands as I highlighted earlier this week.

It will be interesting to see how this chart changes over the coming months as Facebook attempts to double in size to beyond 300 million by the end of 2009.
