But all the average joe or mary has to do is get a phone book and look up the numbers. If they aren't there, they are unlisted.
knowing that number X is NOT in the book is not equivalent to knowing that X actually belongs to someone who opted and paid not to have it in the book, right?
So, except for time I still don't see that Gallup has any different sampling capability than I -- I can know their Listed/Unlisted measure just as well as Gallup.
