[Air-L] youtube users statistics

[Muzammil Hussain]

Hello,

Is anyone aware of articles, studies or reports detailing statistical
information on the aggregate YouTube audience? Demographic info, good.
Psychographic info, even better. Anything related to civic/political uses,
fantastic. I'm aware of Youtube Insight, but the tool seems to be for
specific users, not about the aggregate.

I imagine what I'm asking for is quite elusive, but please do inform me of
any possible leads.

Thanks in advance,
Muzammil
