How do you see viewer demographics of youtube channels other than your own?

[Archie696]

I would like to see the audience demographics (age groups and genders) of popular youtube channels. I know you can view the demographics of your own channel but it doesn't look like it's possible to see the demographics of other channels. Is there a way to do this?

It would give good insight into what makes certain users so popular on youtube and demographics are completely anonymous, no names or identities are given away so I don't see the problem with viewing demographics of other peoples channels.

Socialblade doesn't reveal age group or gender statistics, just viewer and subscriber numbers which gives no insight into WHO is actually watching youtube channels. Any advice appreciated, thanks.
