On YouTube now there is a show video statistics button which shows the statistics of video like view count over time and demography .
I have looked through the YouTube api but I didn’t seem to find a way to retrieve this data.
The closest I could come to was http://code.google.com/apis/youtube/2.0/developers_guide_protocol_insight.html but this is for particular user . I wished to get data available in public .
Yes like mad_scientist said, the public insights for a video are not provided via the API

“YouTube Insight, an analytics and reporting engine, provides viewing statistics, popularity metrics and demographic information for videos and channels.
If you want to get likes and dislikes, and works with c#, you can use this code:
