Aggregating and displaying social networking system user information via a map interface

A map interface presents a geographic map with markers identifying geographic locations associated with content items. When the geographic distance between two or more content items is less than a threshold distance, multiple content items are grouped to create an aggregated content item. Based on the geographic locations associated with the grouped content items, a geographic location is associated with the aggregated content item. A single marker identifies the geographic location for the aggregated content item on the geographic map. When a user viewing the map interface accesses the single marker, content selected from the content items combined to generated the aggregated content item is presented as well as the geographic location associated with the aggregated content item.
