The YouTube Trends Map [youtube.com] is a visualization of the most shared and viewed videos in various regions across the United States over the last 12 to 24 hours. It accompanies the more analytical Trends Dashboard to provide a full overview of the the rising videos and trends on YouTube in terms of actual views or shares, filtered by geographical location, gender or age of the viewers.
The demographic information of viewers is solely based on the information reported by registered, logged-in users in their YouTube account profiles. Next to the geographical map, the Trends Map also include a series of horizontal bar graphs, each representing a graphical summary of the top videos for a different demographic. Within each bar, a video is represented by a colorful segment, the colors are drawn from the video's thumbnail. The width of a video's segment reflects the number of regions on the map where the video is #1.
