body: If I'm looking to build an app or write a book and I wish to use statistics, am I allowed to basically use their numbers as long as I cite where it is coming from? If I do make a profit from it, do I owe any royalties to the original scientists/surveyers? Must I ask them for permission?
  
  
  Currently, the poll data in question is from this website but I'd like to know what's within bounds. The data is from various major media outlets like FOX.

  My intuition pulls me towards thinking that I see books reference hundreds of studies all the time and public polls should be open information to everyone, but on the other hand commercial interests may be legally entangling.
  
  
  I'm not experienced at all in law, so I'd like to hear what you think. Thanks
