The computer program then takes each phone exchange selected and "creates" an actual 10-digit phone number by adding random digits to the exchanges. There is no such thing as an unlisted phone exchange, so the randomly created phone numbers include unlisted as well as listed numbers. The result of all this is a sample of residential phone numbers drawn in such a way that every possible residential phone number in the country, listed or unlisted, has an equal and known probability of being selected into the sample.

this says that gallup (or the group doing the actual sampling from the phone # list) has access to UNlisted phone numbers ... and will treat them as though that level of privacy that is paid for between the resident and the phone company ... does not exist
i would argue (if that really is the case) that this is a clear violation of privacy rights ... since, if YOU tried to find someone's number that happens to be unlisted ... you are out of luck but ... it appears that gallup is not and does not operate by the same set of rules
i am sure this is a small % of the total but, it is disturbing none the less
the ? posed by jill is also important ... how many REAL phone #s had to be dialed BEFORE 1221 (the # they talked to) actually were contacted and agreed to talk? i would venture to say ... twice or 3 times or MORE than the 1221

http://www.gallup.com/poll/FromtheEd/ed0211.aspI found this utterly fascinating. My only question now (which I submitted to the author via the web site) is: what about people who don't answer their phone? Still, more detail than I've ever seen before on their pre-election polling.
