The number of Facebook users in all 22 Arab countries, in addition to Iran, Israel and Turkey, was collected periodically
between April 5 and October 1, 2011, in the following age brackets—youth (15-29), and adults (30 and over).
Raw data on for all Arab countries was collected and aggregated based on Facebook’s official data (Group A), excluding
Syria, Sudan and Iran (Group B), for which data was extracted from a source other than Facebook. Due to US imposed
technology export sanctions, no data on the number of Facebook users in Syria, Sudan and Iran is available.
