I've been working with Youtube Reporting API for about a year. Every month I compare the results between the YouTube reporting API and the YouTube Analytics web interface. I understand that there are small differences between these two systems for certain reasons that are known to me, and that's absolutely fine.BUT it seems to me that the demographic data is sometimes very different, for example this VideoID = y9Y5ZvC-MHg, the overall numbers fit well, but when I compare views sorted by country_code, it is very different. What could be the reason that the demographic data between these systems differ so much?See printscreen and Country France.enter image description here
Logical explanation please
