Number of Facebook users in the Caucasus is a popular topic. I did this analysis with data from Facebook itself.
From the 2013 Caucasus Barometer, we see that 20% of Armenian adults, 16% of Azerbaijani adults, and 26% of Georgian adults use Facebook at least once a week. (Also provided are the percentages out of Internet users.) This matches up pretty well with the Facebook information that had the following for those older than 14 in the countries: Armenia: 25%, Azerbaijan: 19%, and Georgia: 34%.
The Caucasus Barometer also asked about number of friends. This is always difficult because people aren’t sitting at their computers/phones and often have a hard time estimating.
The Caucasus Barometer asked about most frequent Facebook activities this year. See the chart above. I would have loved to have seen all activities asked about separately, as it is hard to really pin down one activity on Facebook, but oh well.
Interestingly, newsfeed reading is the most popular activity in Armenia and Georgia, whereas there is much greater variance in Azerbaijan. I suspect that the variance is due to the use of Facebook as a “free”(ish) space for deliberation in Azerbaijan whereas in Armenia and Georgia there are other places for free discussion.
