Forgive me but I tried to go for the longest post title in history. We’ve been granularly tracking Facebook’s growth since October 2007, which at the time it had a mere 20 million US users. Today it has over 146  million US based users. The following data shows the growth rates of various userbases in Facebook over the one year period from 1/4/2010 to 1/4/2011. All data comes directly from Facebook’s Social Ads system:

Key takeaways:

  1. According to e-Marketer, there are 206.2 million US internet users. That means 71.2% of the US web audience is on Facebook.
  2. The 18-24 (college) demographic grew the fastest at 74% in one year.
  3. Perhaps Facebook’s new “Like” structure drove this metric, but liking “Drugs” is up 1131.9% this year.

I thought it would be interesting to get exact counts of Facebook users based on their specific employment. Seeing as that iStrategyLabs is based in DC it only made sense to check out how our Federal friends were during on “the Facebook”. The data is broken out nationally and by if the employee is based in DC. Also, due to the repeal of Don’t Ask Don’t Tell – I was curious to see how many of our armed forces personel were openly looking for same sex hookups. Keep in mind, the general US Facebook population is 2.01% gay (full report on Gays on Facebook is here). Here goes nothing:
