How to See Other People's Subscribers on YouTube
If you have a YouTube channel, you can view a count and list of your subscribers. However, only those subscribers who have changed their default privacy setting will appear on the list. You can change your default privacy setting in your account settings, and you can also enable subscribers to see your subscriptions on your channel About page in the channel settings. When you view other people's channels, you can see a count of their subscribers, but you cannot see a list of other people's subscribers on YouTube.
View Other People's Subscriber Counts
Sign in to your account on YouTube. Click "My Subscriptions" from the list of choices in the column on the left.
Review the list of your subscriptions that appears under the menu choice you just selected. Click one of the subscriptions to view the channel.
View the number of subscribers to the channel to the right of the channel name, which is next to the option that enables you to subscribe or unsubscribe as of the date of publication. Click "About" under the channel name, and view the total subscribers and the total number of views to the channel.
View Your Subscribers
Sign in to your account on YouTube. Click the menu triangle next to your account name and picture in the upper-right corner of the screen, and then select "My Channel."
Click the link at the top of the page that shows the number of subscribers you have. Review the list of your subscribers who have disabled privacy on their accounts.
Subtract the subscriber count listed on this page from your total number of subscribers to view the number of subscribers with privacy enabled on their accounts.

Sign in to your YouTube account. Locate your account name, and select "Settings" from the menu.
Choose "Privacy" from the Account Settings menu in the left column of the screen.
Click "Keep all my subscriptions private," and clear the check box to enable the authors of the channels to which you subscribe to view you as a subscriber.

Click "About" from the menu in the center of the page.
