To date, few surveys have undertaken a broad analysis of the information needs, channels, and barriers faced by Syrians in accessing social media platforms inside Syria. There is little knowledge of the differences between the use of communication platforms in different geographical locations and demographic groups. REACH has conducted a thematic assessment of social media use, and the channels used in Syria, in order to fill information gaps and better inform the humanitarian community on the ways in which social media is utilised by various Syrian population groups inside Syria, as well as to facilitate better analysis of social media posts.
