About this creator page

Every figure on this page comes directly from the official YouTube Data API or from United States’s daily snapshot history in our database. Subscriber, view and video totals are read from the channels.listendpoint; the videos below are the most-viewed among the channel’s ~15 most recent uploads, shown as official YouTube embeds. We do not publish biographies, personal details or video transcripts — this page is a statistical profile of the channel, not a profile of the person behind it.

The 30-day growth percentage compares the current subscriber count with the snapshot from about a month ago; while that history is still building it reads “Tracking” with a countdown. Average views per video, the engagement ratio and upload frequency are all derived from data already on this page — total views and video count from channels.list, and upload timing from the channel’s recent uploads. Where one of the videos below is also live on our United StatesTrending or Velocity charts, a badge links straight to it. All numbers refresh once daily; the “last updated” date above is the real timestamp of the most recent snapshot.
