Player number statistics

Was wondering if there was any place to find statistics about player numbers such as:

• new accounts created each year
• number of level 30 accounts
• average hours played per account
• how many hours of league of legends have been played total
• number of unique active accounts (however you define active)

etc etc. That kind of information. Just curious since I somehow got to looking up some of this info on world of warcraft and thought it would be interesting to compare (despite the different genre of game).

Thanks
